Title: Replacement parts for Ambient Weather WS-1001 Clone - Maplin N23DQ
Post by: Aircub on May 29, 2017, 03:33:38 AM
Hi I have a Maplin Maplin Professional Solar Powered Wi-Fi Weather Station Code: N23DQ, which I believe is a clone of the Ambient Weather WS-1001.

http://www.maplin.co.uk/p/maplin-professional-solar-powered-wi-fi-weather-station-n23dq

Recently the outside temperature overhead by about 10 degrees when the humidity is high, when its dry it goes back to normal, is it possible to replace the temperature sensor on the outside unit.?

(...)  is it possible to replace the temperature sensor on the outside unit.?

Both stations use WH24 and WH24A (external) and WH25 and WH25A (internal) sensors - both are interchangeable. Important to be configured for the same frequency of 433 MHz or 866 MHz or 915 MHz. Typically, the sensors carry all three bands simultaneously.

After the Ophelia 'storm' my humidity and temperature readings went totally mad.   

From my Maplin N23DQ, the sensor looks very different to others pictured.

I replaced it with a  "SHT30-D Temperature Humidity Sensor Breakout 3.3v 5v For Arduino Arm RPi ESP8266"  I found on eBay.    The pins are not in the same order.

Very pleased it is up and running - just hoping I have silicone sealed it well enough, although the sensor itself is exposed.   

Should the little circuit board be sprayed with something inert but water-repellent ?

at the top of the radiation shield where it meets the rest of the unit apply silicon this also where the water tends to leak through , and can be problematic during dense fog.. self amalgamating tape from b&q or some plumbing shop in the uk or even maplins might sell it .just wrap a small piece around the circuit board leaving the sensor exposed..basically condensation does build up and sends your reading awol ..dew,water all act as a conductor !...brian

Thanks for the detailed advice.

I have sealed the hole where the shield is attached to the main body of the PWS, and the hole through which the wire goes.  So I hope that water cannot be blown through the shield up into the batteries/electronics.

It was quite noticeable how dirty the old sensor was, but even after I had gently removed the grime with isopropanol, I could see apparent corrosion damage to the circuit board tracks (see my cleaned up picture showing where I had checked for continuity under the corrosion)

I suppose it is a perpetual problem - the sensor has to be in free flowing air, so it will get contaminated eventually (18 months in this case).

If you look the photo you can see the exposed solder points so only need a small amount of water or condensation across the solder points and it will go erratic , when I owned one I particularly paid attention to that area after addressing that area I had no more erratic readings regardless of heavy rain in our case flash floods and heavy dense fog I live 150 meters from the sea so prone to dense fog during the cooling months , in fact you can watch the fog flow through the air at times when it is really dense . I would definitely address that circuit board area .

Have fun and if you live in high UV area like here in Istanbul the wind vane will eventually break mine crumbled in my hand when I took it down a month ago..the plastic is not uv resistant and it just turned in a Bakelite powder literally as I touched it, if a bird sat on it would have broken long before.

Expected life of these models 3 years max and trash it sadly but they give you a good insight into the hobby.if I hadnít gave it away I would have salvaged the solar panel for another project ..

I use Conformal Coating Spray to seal my circuit boards and solder joints. You also get it in brush on which is great, as you don't have to mask items that must be left open such as the sensor opening.

Hi.
I have an Ambient Weather Clone (sold as MiSol).
For more than a month my outdoor unit is not reading the humidity correctly, always shows higher values than any other unit close to it, and at night it usually shows 99% humidity until sunrise, and sometimes the display shows - - %.
I read some topics about this problem, but it seems that Ambient Weather (and Fine Offset) doesn't sell spare parts (sensors). And I'm not going to buy a new outdoor unit just because one bad sensor.
Does anyone know if it's possible to find the sensor (OEM) to replace the bad one, or if there is a way to replace the sensor with another one, a "generic" sensor with the same specs?
I tried to remove the batteries and cover the solar panel to "reset" the unit, but it didnít make a difference. So, as the sensor is not working as it should, I tried to clean it by spraying clean water and let it dry, it didn't make a difference. So, I put three hygrometers close to the outdoor unit to know what the humidity was and I changed the calibration on the console, since the humidity today is something between 50% and 60% it seems to be "working", but I doubt it will read the correct humidity when it is really high.

Try to find the same little circuit board online - wherever you get it in the world it is so timy that the postage will only be the cost of a letter.

Good Luck !

Can I replace the original sensor with the SHT30 / SHT30-D board? Because the original sensor board I can't find it for sale.

I bought two of those little boards. Now is just a matter of waiting (a lot of time) to get it here and also to learn which wire goes to which connection on the new sensor. It was really cheap, but the problem is that it takes 40 to 60 days for the awful, slow and corrupt Brazilian customs to release it from "their hands" .... that is the price to pay for being born in a third world country.  :?

I would just like to thank everyone for the useful info my Maplin clone croaked earlier this week I bought a SHT31-D from Ebay

one of these
https://www.ebay.co.uk/itm/182116692919?ViewItem=&item=182116692919&clk_rvr_id=1505314044227&mfe=si_en-GB_itemClick&mpt=1524239464434

The version with RH connector already soldered on

Once connected it is a 100% compatible part and my weather station is 100% again
In fact the temp is now more accurate as well.

I also updated the Maplin firmware to V2.46 from the Ambient site probably no value in doing so but I wanted to use the "EasyWeatherIP" software rather than the screen buttons to configure the unit and assumed I best use their firmware as well

My Maplin clone has also started reporting humidity 99% Temperature 60į. I'm really keen to replace the module but don't know which wire is which. Is it obvious when I strip the sensor down? Can anyone help, I'm sure it's easy but I'm nervous. Thanks in advance.

Post by: senrabyar on May 14, 2018, 04:58:53 PM
Be brave. 

Take pictures at each stage in case you want to show them on this forum. 
Write down which wire was connected to which code on the old board.
If two wires have same colour, do something to make them unique before disconnecting. 
Both the old and new circuit boards will hopefully have same codes. So easy then. 
If you cannot match the codes, send the pix here !

Good luck.

Finally!! the sensors arrived.

I bought two, just in case..... and also bought a set of bars with pins and connectors.
Now is just a matter of disassembly the outdoor unit and try to find out how to solder the wires in the correct order...... let's see if I'm able to do it.

So, here we go...

I removed the radiation shield to try to find out how to install the new sensor, since it has a completely different shape.
(https://i.imgur.com/awoDXMS.png)

First I thought that I would just to insert it in the slot that the old sensor was (I just had to cut the two little tabs that hold the original sensor in place) but it was a bad idea for two reasons, first because I accidentally broke a small plastic piece with one of the capacitors on the back of the new sensor board, damaging the board (luckily I bought two of them), the second the reason is that the sensor was too close to the top of the radiation shield.
(https://i.imgur.com/HENYKSm.png)

So, I used a flat piece of plastic to create an extension to install the sensor more or less in the same position as the original sensor was. I used hot glue to hold the piece of plastic in place and glued the top of the board to the piece of plastic. After soldering the wires I applied a coat of transparent nail lacquer to try to protect it from moisture.
Also, I was able to "save" the glue on the top, so I reused it to seal the top of the radiation shield (using hot glue to put it back in place).

(https://i.imgur.com/jEHu0gA.png)
(https://i.imgur.com/5QxE2AD.png)
(https://i.imgur.com/5KhW4Kb.png)

Then I put everything back together ... and.... it worked! The sensor works really well, the readings seems to be very accurate.

Thanks for the pics.  :-)  I might need them when mine stops working!  I got the original unit replaced under warranty and so far (fingers crossed) the new one is still working.  Mine is a Maplins ws1001 clone and the warranty is up in August.  Maplins have now ceased trading anyway so I'm on my own for any back up.  I'll just see how long I can keep it going by repairing it myself if it goes wrong.

I really bought it mainly for the anemometer function but I have found the rainfall data useful via WG when we are away to see if the garden is likely to be drying out.

Oh, I forgot to mention. When I was opening the outdoor unit to replace the sensor I notice that it didn't turn off when I took the batteries out ..... yes, it has a supercapacitor inside, so mine is the same model sold as Ambient Weather 1002. Nice suprise.  \:D/

Have the N23DQ ( 3 years old )who had stopped working with his temperature, looked online and found this side, first thing what I like to say is that all the people like to help what I have read so far. I found my answer here, and like to THANK YOU for what need to do in the first place. The pictures helps, step by step. very nice. I have installed the SHT31 SHT31-D Temperature & Humidity Sensor Breakout Board Weather Module f G2G1, Ordered from ebay and installed, and works fine for now,. and thanks again.

Hey all
i just want to ask if i can use another sensor than the one you all used, since it take a lot of time to reach my country..
For example can i use this :-SI7021 Temperature and Humidity Sensor Breakout

Sorry to revive an old thread but I have this same problem.  I have a new SHT30 but the old sensor isn't labeled at all.  On the board in the station the four connections are marked TH1 TH2 RH1 & RH2 with a red striped wire going to TH1.  No indication of Vin or GRND.  Could anyone tell me which of the four connections above relate to Vin GRND SDA & SCL?  I've tried wiring it in but I'm getting 99% RH an -20c on the console now???

Wow you are a member since 2016 and this is your first post! What took you so long? Just kidding with you and giving you a hard time. Good to hear from you and welcome.

Doesn't sound like you have the same weather station model being discussed in this thread. What brand and model weather station do you have?

The SHT30 is a serial digital device utilizing the I2C bus protocol. This means that both temperature and humidity get transmitted via the same 2 wires (the serial I2C bus). The other two wires on the SHT30 are for power. On your device based on the names of the 4 connections it seems like some other method that is not I2C is being used. To me TH1 and TH2 sounds like are wires used to transmit Temperature, and RH1 and RH2 sound like are used to transmit Relative Humidity. There is no dedicated power wires like in the SHT30 because I think your system is using an analog method of data transmission. This is all a guess. I could be wrong. We will know more once you give us your station brand and model. It could be that you may have a older version that didn't use digital and used analog yet it still looks like the pictures of the station in this thread. So it doesn't seem like the SHT30 would be compatible. They do make an analog version of the SHT30 but I'm not sure that will work either. I think you have something else all together.

Post by: freightdog on February 07, 2019, 01:53:30 PM
Thanks for the info. My station is a Maplin N23DQ. It's been okay up until now, although the rain gauge died last year. But now the temperature is over reading,I thought it was time to try and fix it.  I think I've fixed the rain gauge by wiring in a new reed switch.  I ordered the SHT30 after looking at this thread, but after opening up the station I found the temp/humidity sensor is a little different and not labelled.  I tested the the board and appear to be getting about 2v off the TH2 pin and GRND from the RH1. So I wired those accordingly and put TH1 to SCL and RH2 to SAA but I'm getting temperatures of +58 and RH 99%.
So I guess it's either still wired wrong or the sensor is bad.

freightdog,
Your Maplin N23DQ is of an older generation. It doesn't use the digital SHT30 SMD chip. Instead it uses an analog humidity resistor and a thermistor thermometer also analog. The pairs of wires are each for a separate sensor.

See this for a picture (you can see both sensors):
http://www.wxforum.net/index.php?topic=30689.msg324655#msg324655

See here for reference to both parts:
http://www.wxforum.net/index.php?topic=30689.msg326024#msg326024

Essentially these are the parts you need:
HR202L for humidity
NTC-MF52-103/3435 for temperature

Post by: freightdog on February 07, 2019, 02:46:45 PM
Ah.. well that would explain it then!  I shall try and source those parts and see if they will make a difference.

Thank you Galfert for all your help, it's very much appreciated.

Post by: galfert on February 07, 2019, 03:08:51 PM
There might be another solution. I say might because I don't know enough about this. So it might be possible to convert the output from the SHT30 to analog using an digital to analog converter. Perhaps this is not the correct device to use...but maybe something like it. Or maybe you need two of these since I only see one analog output pair...which might mean that you need two SHT30 and then each of the digital to analog converters one does themometer and the other does humidity.

https://learn.sparkfun.com/tutorials/mcp4725-digital-to-analog-converter-hookup-guide?_ga=2.20162616.1823937908.1549569423-1074852380.1549081028

Probably not worth the trouble. But I just thought I'd mention it in case this was your sort of thing to figure out.

Another option is to realize that your weather station is pretty dated. The fact that you've kept it going this long is impressive. So you've fixed the rain gauge recently and now you need to fix the temperature and humidity sensor....so what will break next the wind? My point is that these are not expensive weather stations....Maybe you should consider a new WH2900 or WS-2902A that will have much better sensor parts and is more accurate in all respects. This newest generation is very good at wind direction and doesn't flap as much in the wind for direction. Also it uses a supercapacitor so you don't need to use rechargeable batteries. That and more. Your call. Just wanted to inform you that technology has advanced and that there is not just new stuff available but new better stuff as not always is new stuff really better.

Well if I can fix it few a few quid then happy days! But if not, then I agree a new one will be the best option.
