Gravity - MEMS Gas Sensor - CO, CH4, H2, NO2, NH3 - I2C - MiCS-4514 - DFRobot SEN0377

Index: DFR-20378 EAN: 6959420920594
Gas sensor with integrated MiCS-4514 chip made with MEMS technology. What does the gas sensor react to? First of all it detects various harmful gases and volatile organic compounds like carbon monoxide (CO), methane (CH4), ethanol (C2H5OH), hydrogen (H2), ammonia (NH3) and nitrogen dioxide (NO2). The sensor only detects the concentration of gases in the air - it does not differentiate between them. The module is intended for educational and hobby purposes. Proper operation in medical, protective or similar applications is not guaranteed.

Special features

  • The sensor detects only the concentration of gases in the air. It doesn't distinguish between them, so you can't tell which gas was detected.
  • Low power consumption and I2C communication interface.
  • Compatible with any controller powered from 3.3V to 5.5V, e.g. Arduino, ESP32 or Raspberry Pi.
  • Used in gas leakage detection projects.
  • It can be used as an actuator during environmental air testing.
  • The module is intended for educational and hobby purposes. It is not guaranteed to work properly in medical, security or similar applications.

Contents of the kit

  • Gravity - MEMS gas sensor - CO, alcohol, NO2, NH3 - I2C - MiCS-4514 - DFRobot SEN0377 - 1 piece
