DFROBOT SEN0574 Breakout Kit, GM-102B, MEMS NO2 Sensing, DFRduino UNO R3 Boards

SEN0574 is a Fermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor breakout board. It employs state-of-the-art micro-electromechanical system (MEMS) technology, endowing the sensor with compact dimensions, low power consumption, minimal heat generation, short preheating time, and swift response recovery. The sensor can qualitatively measure the concentration of nitrogen dioxide gas, and is suitable for nitrogen dioxide detector, automobile exhaust detection, and other application scenarios. Suitable for Air quality monitoring: measures the level of NO2 and other pollutants in the ambient air. Automotive emission control: monitors the NO2 emission from vehicles and adjusts the fuel injection and combustion parameters to reduce the emission. Industrial safety: detects the leakage or exposure of NO2 and other toxic gases in industrial processes or workplaces applications.
