    Auriol weather station humidity sensor

    I have two Lidl LD6273 Auriol units with DCF77 radio for time update.
    I really like the idea but the cheap moisture sensor(guess HR202L) inaccuracies make the device unreliable. Also not clear why indoor and outdoor unit sensors being same type doesn't match. For example I place both units on same table and indoor unit shows 23% humidity while outdoor sensor shows 39%. What I found out is that I get better readings if cleaning the solder points of sensor inside with isopropyl alcohol.
    Looking for replacement sensor which I could solder in place of HR202L resistive sensor but need to have similar characteristics. Or there is issue with wrong PCB schematics?

      AcuRite 5 in 1 temperature sensor replacement repair
      by CapLeaker
      Got a new victim:

      AcuRite 5 in 1 Iris outdoor weather station not updating the temperature / humidity anymore. The original sensor is a SHT21. Also there are identical other sensor manufacturers. I chose the HTU21D to replace the original SHT21. Both have identical specs. I've had two failure modes with these sensors.
      A: outside temp stuck at -40? It's cold here at times in Canada, but not that cold!
      B: stuck at some temperature and maybe updating once in 12 hrs or so.

      Easy solution is to go to AcuRite website and purchase the sensor. Right?...

      Egg incubator humidity sensor replacement
      by unimatrix93
      Hello everyone,

      My egg incubator humidity sensor kicked the bucket, I read open circuit on it with DMM even in the MOhm range.

      So I started identifying this piece of crap and look for a replacement part.


      This thing has 6 turns or black lines, while the one I found similar has more turns and has 33kOhm. ​
      Based on the number of black lines, this one looks like the 23kOhm version of this thing, but I cannot find anything with this value on the local distributors.

      I assume the 33kOhm wont work?
      What do you guys recommend?...

      Sensor error on my hot air station.
      by MaineFix
      Hello, so i have a quick tr1300a hot air station. I keep getting a sensor error on my display. I don't know what i should do. The company that sold it to me is not willing to work with me and i don't know what I should do. I have only had it about a month. I called the company and they told me that I could probably fix it but I don't know what i am supposed to replace/fix nothing online has any information about it other then a 18 second YouTube video and a guy in the comments saying he replaced the joystick on it but I have never heard anything on a hot air station called a joystick. Any and...

      Meaco Arete One / Deye Dehumidifier not working
      by CG2
      I've got a dehumidifier that has stopped working. Plug it in, press the power switch, and it beeps 5 times. Nothing showing in the display (which is just two 7 segment displays) apart from the two decimal points flashing. The model is a MeacoDry Arete One 18L, which seems to be a rebadged Deye (all the boards are marked Deye). Here's what I've got so far (details in case anyone else in future should need them).

      Starting with the power board. Mains power comes in at the red connector top left. The compressor is powered by the orange connector to the right of that and is switched by...
