Arduino MQ2 Gas Sensor Brick -1
By using electronic bricks, you may connect Arduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos...even buttons, just plug and play.
Each terminal module has buckled port with VCC, GND and Output, which has corresponding port on the sensing board, with a plain 2.54mm dual-female cable you may start playing already. Buckled brick cables are like cement for bricks, make the connections easier, secure and more professional looking.
It is very interesting Electronic Brick Module
This module can be used with Arduino Special Sensor Shield V4.0.
You can do some simple design about it，it support“plug and play”。

This sensor module come with 3 Pin Dual-female Jumper Wire length 300mm as below :
Description :
MQ-2 Semiconductor Sensor for Combustible Gas
Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensors conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application.
Electrical Parameter :
1、Heating voltage: 5 + /-0.2 V (AC · DC)
2、Circuit voltage: 10 V (maximum DC 24 V)
3、Load resistance: 5 K (adjustable)
4、Clean air voltage: more than 1.5 V
5、Sensitivity: 3 frequency
6、Response time: more than 10 S
7、Turnaround time: more than 30 S
8、Components power consumption: more than 0.7 W
