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.?

Thanks will take a look at the sensors when I get a free moment.

(...)  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 ?

Can you give the Ebay link, my reading have gone haywire too.

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.
