TMP36

by nhodgson5 on Tue Jan 02, 2018 3:19 pm

Hi, I ordered 30 TMP36 sensors to use in my classes and the majority of them seem to not be calibrated. Going by the tutorial on the adafruit website, the voltage being read from the sensor should be about .75 V at room temp, but we're getting about .55-.65. Any thoughts? Thanks

How are you testing these and what readings are you getting at what temperature? At 20 C ( 68 F )you should get 0.70

With a voltmeter and through the Arduino's serial monitor--getting the same readings. In a room temp classroom.

What is the temp in the classroom and what are you powering the TMP36 with? What is the meter giving you at that room temperature?
