Electrochemical carbon monoxide sensor CO Evaluation Module for TGS5042 EM5042A 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 concentrations, CO gas concentration can be calculated from the measured output voltage values (*2)(*3).

*1For more details of characteristics and performance of TGS5042 sensor, refer to Technical Information for TGS5042.

*2The main function of this module is to simply convert sensor output current into voltage output without temperature compensation.

For more information on a temperature compensation circuit, refer to Application Notes for TGS5xxx or contact Figaro.

*3A calibration curve is available upon request if this module is ordered together with the sensor.

The calibration curve represents the relationship between CO gas concentration and output voltage of the module with a particular sensor. The calibration curve is provided for reference purposes only
