Maplin wifi weather station type N23DQ outside temperature problem.

[Stephen A]

I have had one of these weather stations for 6 years now and has proved reasonably reliable. It's on the second set of rechargeable batteries in the sender which is up a pole on my roof. Occasionally the external temperature reading goes haywire. This morning when I got up it was reading 10C outside when it was more like -3C with freezing fog and a thick frost. If you leave it for a day or two it sorts itself out and starts reading normally compared with AccuWeather. I am just wondering if the batteries starting to fail again as it usually occurs when there is very little sunlight light to charge the batteries up? It means getting the ladder out to take the head unit down to examine which is a bit of a nuisance but maybe it needs a 3rd set of batteries. The rest of the functions are fine, just the external temperature the throws a wobbly.

Has anyone else with one of these stations experienced the same problem?

Yup (-: Try replacing the batteries with non rechargeable lithium..  Failing that it's the temp/humidity sensor playing up -  a web search will find a replacement for your make and model  - good luck

 

could be one of these but you'll have to open the station up to find out for sure :

 

BMP280 5V Digital Temperature Barometric Pressure Sensor Module

The board is tiny, yet very capable and easy to use. This can be powered from and connected to either 3.3V or 5V devices without modification. Temperature Sensor Range: -40-80°C, Accuracy: 1.0 °C...
