    Egg incubator humidity sensor replacement

    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?

    if the other one has more turns, then shorten it!?

      It's a humidity sensor, it measures humidity (moisture) between the conductors, when there is moisture on it it will measure impedance at the operating frequency, this parti s unlikely the problem
      HR202

        However I cannot measure any resistance on it, my DMM measure open circuit on it.
        I will check the surrounding circuitry on the main board, just in case.

          No you can’t measure resistance with your DMM on that, It just will s how open circuit. As long as that thing is in one piece, no cracks and the wires have continuity to it, that type of sensor or actually more like an antenna is fine. I’d be more concerned if there is a short or a reading on it.

            Google Pixel 5 - Proximity Sensor Issues - Reflow/Replacement procedure tipps wanted
            by groomit
            Hi,
            I just replaced the battery on a Google Pixel 5.
            After that the proximity sensor isn't functioning properly any more. It is constantly activated. So when playing a voice message on Whatsapp, the Screen instantly turns off.
            Checking with a sensor app I can verify weird behavior of the sensor. It is triggered when nothing is near and sometimes works correctly when squeezing the phone next to the sensor hole.
            The rubber seal is on again (as mentioned in various suggestions in other forums).

            This smells like a cold or broken solder joint. So I'd like to reflow...

            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?...

            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...

            Auriol weather station humidity sensor
            by otoluk
            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...

            Dell Latitude 5570 Ambient thermal sensor reading -127 Degrees C
            by Gcnewbie
            Forgive me this is my first request for help on this forum, so if i've screwed up or not followed the rules i should have i apologise profusely.

            I have a Dell Latitude 5570 that was randomly shutting down, on further investigation i found that the machine had been shutting down due to thermal events as noted by windows event viewer.
            My investigations lead me to the dell diagnostics screen, where i found that there were two sensors out of range which had been causing the shutdowns, one of which was the GPU thermal sensor and the other the ambient sensor.
            I opened the...
