Fermion: MEMS CH4 sensor employs state-of-the-art microelectromechanical system (MEMS) technology, endowing the sensor with compact dimensions (13x13x2.5mm), low power consumption (<20mA), minimal heat generation, short preheating time, and swift response recovery. The sensor can qualitatively measure methane gas concentration. The MEMS series currently encompasses 11 different types of gas sensors (HCHO, CO, CH4, VOC, NH3, H2S, EtOH, Smoke, Odor, H2, NO2), which can be combined as per specific requirements. Please note: This sensor is capable of qualitative measurements only. For quantitative measurements, kindly consider purchasing the [Factory-calibrated Gas Sensor](https://www.dfrobot.com/product-2510.html).
