Acurite 00592tx Tower Sensor info

[Gazza]

I have an Acurite 00592tx Tower Sensor working with the SDR driver and noticed that it is emitting humidity data.

This version of the sensor is supposed to be temperature only so I opened it up and found that it is configured to send both temperature and humidity but there is no humidity sensor installed.

A bit of a long shot but does anyone know what type of humidity sensor is used in the 00592txr version ??

Hi Andy,

From the pictures at wxforum it looks like an analogue capacitive humidity sensor, if I can find one I'll try it out.

Now that the Digoo (Nexus) sensor works and the other cheap ebay Prologue sensor I got also works I have enough dual temp/humidity for what I want.

Let me know if you find the humidity sensor, I have a 592x  needs one.

I picked up a few HR202L Humidity Sensor from ebay, they are advertised as a "resitance humidity sensor" and look similar to the pics in the wxforum thread and were only $1.85 for 5 so worth a try.

With the sensor installed the results have changed from the constant "16" to a value that changes with a change in humidity but it does not relate to the output of another sensor sitting next to it.

So probably not the correct part so will keep looking, I am also going to set up a separate test system on a spare Raspberry Pi when a new SDR receiver arrives so may do a longer term comparison then.
