The EM5042A evaluation module is designed to perform the testing and evaluation of the electrochemical carbon monoxide sensor TGS5042, which features high selectivity to CO, high repeatability and a long life.
This module is useful for evaluating basic performances of TGS5042 gas sensor, and as a reference of application circuit.
Operation:
The TGS5042 CO sensor is placed into the sensor socket. EM5042A goes into normal operation within one minute after first being powered on. If CO gas is not present in ambient conditions, output voltage is 1.0V. If CO gas is present, the output current generated from the TGS5042 sensor (*1) is converted into output voltage. A linear relationship exists between output voltage and CO gas concentration. By measuring in advance, the output voltage in a known CO gas concentration, CO gas concentration can be calculated from the measured output voltage values (*2) (*3).
