I ran the camera in cold environment, with a target T° of -30°.
At the first run, the measured temperature didn't change. I needed to disconnect the camera and reconnect again / restart Maxim to have the temperature from the sensor changing.
Then, when reaching around -30°, the sensor temperature continuously changed from -29.7 to -30.9°C.
I made a trial on an other computer, in room temperature.
With a setpoint of -5C, the sensor T° jumps from -4.5° to -4.9°; the TEC power was about 52%
Going from -5° to -10°, then the sensor temperature changes:
Then the temperature is unstable: -9.4, -10.0, -9.4, -10, etc.
The TEC power is 69%.
I wonder the behavior of the sensor T°
All cameras that I used show a precision of 0.1°, with a control at the target.
Also the ASI1600 doesn't not show strange behavior of the cooling control.
Is something wrong with this ASI294MC?
