MQ2 Methane LPG Smoke Hydrogen Gas Sensor – India

Description

Circuit Uncle has procured Methane Butane Propane LPG Smoke Hydrogen Gas sensor MQ2, for its inventory for you to buy online in India with fast shipping. Build your own very generic gas detection circuit at budget, with an MQ2 gas sensor. This sensor detects a variety of gas present in the air. They are used in gas leakage detecting equipment in the home and industrial settings, and can be used to detect LPG, i-butane, propane, methane, alcohol, Hydrogen, and smoke. There will be very little effect of temperature or humidity on its working, thus, result in a very stable output. You can purchase with Circuit UncleArduino UNO or Arduino MEGA to build your own cost-effective gas leak detection solution.

The MQ2 gas sensor is made through micro AL2O3 ceramic tubes, Tin Dioxide (SnO2) layer, measuring electrode and heater are fixed into a crust made by plastic and stainless steel net.

Datasheet of MQ2 Methane Butane Propane LPG Smoke Hydrogen Gas Sensor

NOTE: MQ2 sensor’s sensitivity needs to be adjusted before the use, and it is recommended to calibrate the MQ2 gas sensor for 1000 ppm liquified petroleum gas (LPG), or 1000ppm iso-butane concentration in air and use-value of Load resistance that about 20 KΩ (5 KΩ to 47 KΩ).
