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

The SHT31 works great in my HP1003 station !

 I have to reset the outside unit and the sensor needed some time to show the correct values.

Thanks for the nice howto pictures !!!

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.

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

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.

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.
