MQ-2 Flammable Gas and Smoke Sensor - HobbyTronics

The MQ-2 Flammable Gas and Smoke Sensor detects the concentration of flammable gas and smoke in the air and ouputs its reading as an analog voltage. The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V. Connections. Connecting five volts across the heating (H) pins …
