AM2315 Digital temperature and humidity sensor

Post by Kimdongmin »

Excuse me
Can i ask you a question about the AM2315 product?
Several AM2315 products were measured at the same time, same space, but the temperature was differentt
The temperature is 2~3℃ different
Is there a way to initialize the setting value or match the two product temperatures

The manufacturer's accuracy spec on these is +/- 1℃. And environmental factors such as heat producing devices like computers can create substantial temperature gradients in a rather small space. So 2~3℃ difference without tightly controlled measurement conditions is not that unusual. For critical applications, calibration is the place to start.

We have a guide on sensor calibration here: https://learn.adafruit.com/calibrating-sensors
