Hello!
The Atmotube Pro Android app has calibration/offset settings for the humidity and temperature sensor, but the new Atmotube Pro 2 for Android doesn’t have these settings (app versions 3.0.19 and 3.0.20). On iOS, Atmotube Pro 2 does have these settings. When do you plan to add this feature to Android users?
Hi Vladimir,
Normally, calibration is not required for the PRO2 device, as the sensors are factory-calibrated. However, if you are seeing a noticeable difference compared with a reference device, it would be helpful if you could share some comparison data.
In the meantime, you can adjust the offset using a USB UART command:
calibration [t_offset] [h_offset]
The offset shifts the base device calibration.
Parameters:
[t_offset] – temperature offset
Float value from -5.0 to 5.0
[h_offset] – humidity offset
Integer value from -10 to 10
We do plan to add calibration/offset settings for PRO2 in one of the upcoming Android app releases.
Hello!
Using a salt test, I determined that the Atmotube Pro2 (s\n ROUAB25903A5) is underestimating relative humidity by 7% (68% instead of 75%). Are there instructions on how to calibrate it using the USB UART command?
The instruction is quite simple:
screen /dev/cu.usbmodem1101 115200 command to open the port or any similar app (like Serial)
