I just today assembled the RF22 Temperature Sensor and tested it. It seems to be working, except for the temperature reading. I've searched the posts for a while and haven't found anything resembling my problem. Running rfthermtest.py or rfsensor.py the temperature is usually around the 180s in Celsius. The temperatures it has given so far are 182.80 C, 185.60 C, 188.50 C, 191.60 C. My house is obviously not this hot inside. I'm thinking that the thermistor is what is messed up and I might need a new one, but I was hoping someone had this problem and resolved it or at least someone can confirm that my thermistor is broken.

Can you take a close up picture of the thermistor and resistor?

I attached the images to this reply.

We shipped the wrong resistor. The resistor you have is a 1M resistor and you need a 10k resistor. Very sorry for the inconvenience. We can ship you the right resistor.

Ohhh okay. I would appreciate receiving the correct resistor. How do we go about doing that?

Please email your order number to sales.pri...@gmail.com or reply to the sale confirmation email so we can find your postal address and we will ship you the correct resister asap.

You 10k resistor is on its way. We also included a mini breadboard. Apologies for the inconvenience.

Jonathan

Hi Kristian,

Look at your shipment I see you ordered the AK09. That kit has three 10k resistors in it, one of which you could use in the mean time to correct the rf sensor issue you have.

Regards,

Jonathan
