Product Description
This 4LEL-Smart Module PCBA consists of a data collection and processing PCB assembly, and a SemeaTech 4-Series Catalytic combustion (LEL) sensor. The PCB assembly in the module collects the data from the gas sensor output, and then processes it with amplification, sampling and filtration through a built-in MCU to deliver stable and accurate digital output reflecting the actual target gas concentration. The 4LEL-Smart Sensor Module 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. Users can visit the website for detailed sensor parameters.
