This is a 3.3/5V compatible MEMS gas concentration sensor from DFRobot.
This sensor supports the detection of various gas concentrations like CO, C2H5OH (Alcohol), H2, NO2, NH3, and integrates various gas concentration conversion formulas in the code to facilitate the testing and use of sensors.
With I2C output and 3.3~5.5V wide voltage input, it is compatible with Arduino, ESP32, Raspberry Pi and other mainstream controllers.
