Circuit Playground Temperature Sensor
Hello! My students are using the Circuit Playground Classic temperature sensor. The values it's returning have consistently seemed very high (by about 10 degrees). Has anyone had this issue? Thank you!

Re: Circuit Playground Temperature Sensor
The thermistor is located within a 1/4" to the processor so you should expect slightly elevated temperatures over the room ambient temperature.
Just curios which example code are you running and is it Arduino, CircuitPython or Makecode based?

Re: Circuit Playground Temperature Sensor
Thank you. I'm using Arduino and the temps are running a bit high and I intuitively told the kids that it was likely just ambient heat, so I'm glad that could be the answer. I can try to calibrate it over the temperature range we are using in the code to read a bit lower.

Re: Circuit Playground Temperature Sensor
You could plug in an external temp sensor to help with calibration. You could compare with the results with the onboard thermistor directly. You'll also want this adapter cable.
