The 4SMART-C01 sensor module is designed for 4-Series three-electrode electrochemical sensors, which serves as a modular detection platform for real-time concentration detection of various types of toxic and hazardous gases in the environment. The module takes SemeaTech electrochemical sensor as the sensitivecomponent (specific technical parameters of the sensor refer todatasheet) and performs gas concentration detection throughsignal sampling, amplification, filtering, and conversion. It features built-in temperature compensation, linear correction, and other functions, ensuring excellent stability. It supports UART and DAC signal output modes, allowing direct output of digital and analog voltage signals that represent gas concentration data. The user-friendly design simplifies operation and reduce users' development cycle. It also includes an automatic shorting PIN function for zero-bias power failure, enabling stable operation within minutes of power-on for unbias sensors. For biased sensors, it is recommended to power on for ever 24 hours before use.
