modMQ-2 - module with a sensor for concentration of combustible gases and smoke

The MQ-2 sensor allows the measurement of gas concentrations such as propane, butane, methane, LPG as well as alcohol and smoke. Sensor measuring range: up to 10,000 ppm

The module allows the detection of volatile organic compounds (VOC) in the air, based on Winsen\'s WSP2110 system. Allows for detection in the air; formaldehyde (HCHO), methane, benzene, toluene, alcohol, etc. The sensor output is an analog signal. Seeed studio 101020001
