Gas Sensor LPG, Propane, Hydrogen MQ2 Module

Product Code: A026

Availability: In Stock

Price: Rs. 250.00


This is a very easy to use and very handy gas sensor  ,suitable  for  sensing  smoke,  H2,  LPG, CO,  alcohol,  Smoke,  Propane  cocentration  in  the  air.  This  sensor  MQ-2  can  detect  gas concentrations  anywhere  from  200  to  10000ppm.  The  MQ-2  sensor  has  a  very  sensitivity  to Propane, Hydrogen, methane and LPG. 

  The  sensitive  material  of  MQ-2  is  SnO2, which  has  lower  conductivity  in  clean  air. When  the target gas exist, the sensor’s conductivity is higher along with the gas concentration rising.  The sensor  could  be  used  to  detect  different  combustible  gases  especially  Methane.  It  is  very  low cost and suitable for different application. This sensor can be used to make wireless Gas leak detector in home security system. 

This sensor has a very simple; all you need to do is power the heater coil with 5V, add a load resistance,  and  connect  the  output  to  an  ADC.  This  is  a  very  simple  easy  to  use  LPG  gas sensor,  suitable for  sensing  smoke,  H2,  LPG,  CO,  alcohol,  Smoke,  Propane  concentrations  in the air. This sensor has a very fast response time and high sensitivity. The connections are as follow: First connect the Vcc pin to 5V with the microcontroller, and connect your GND to GND pin of arduino. Connect the AO pin to AO pin of arduino.
