Product Number: ADUCM355
Hi,
Based on the CN0429 demo board I have written a ADUCM355 firmware to constantly measure current and voltage on the NO2 electrochemical sensor. I have colocated the sensor close to the NO2 reference station. What I have noticed over 1 month period is that measurement data have multiple calibration curves in the mesurements data set. I assume this is caused by the temperature dependence and daily temperature variation. I excluded temperature dependence from the equation. Can you tell me more information if ADUCM355 chip has to be somehow temperature compensated? Does RTIA resistor change it's value due to the temperature?
Best,
Michał
