Model 4ECM -4-Series Smart Gas Sensor Module
This 4ECM-Smart Module PCBA consists of a data collection and processing PCB assembly, and a SemeaTech 4-Series electrochemical (EC) sensor. The PCB assembly in the module collects the data from the gas sensor output, and then processes it with amplification, sampling, filtration, and temperature compensation through a built-in MCU to deliver stable and accurate digital output reflecting the actual target gas concentration. Any of SemeaTech 4-series EC sensors can be used to form a 4ECM-Smart Sensor Module that delivers the signal output through UART bus, which provides a good user experience for quickly integrating gas sensors into the existing systems for a variety of gas detection applications.
