Fermion: MEMS Nitrogen Dioxide NO2 Gas Detection Sensor

Fermion MEMS NO2 sensor uses state-of-the-art MEMS tech, with compact 13x13x2.5mm size, <20mA low power, short preheating, swift response. It qualitatively measures NO2, suitable for NO2 detectors, auto exhaust detection. The MEMS series has 11 gas sensors (HCHO, CO, CH4, VOC, NH3, H2S, EtOH, Smoke, Odor, H2, NO2) for combination. Note: Qualitative only; for quantitative, buy Factory-calibrated Gas Sensor (https://www.dfrobot.com.cn/goods-3423.html).
