Sensor module for DM03 and WPD / CA3 detectors

The CA3 sensor module uses the most modern CO measurement technology; it uses a professional electrochemical cell. In addition to the CO measurement circuit,
the CA3 module integrates a non-volatile memory where the production parameters, type of gas, calibration concentration, production date, serial number, etc. are recorded.

The detectors also use part of the memory of the CA3 module to record the hours of operation and other events such as alarms. The CA3 module, guaranteeing a 5-year life,
allows to extend the life of the DM03 and WPD/CA3 detectors from 5 to 15 years by replacing the module twice.
