Arduino MQ7 Gas Sensor Brick

We can build electronics projects just as easy as piling bricks. Arduino and community have made the programming much easier than ever before. How about some elixir on hardware part? Maybe it is not yet convenient to make complex interfaces, but we can at least start from the most commonly used modules.

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 brick comes with a MQ7 gas sensor, you can adjust the sensitivity with the potentioneter.
Description :

MQ-7  Semiconductor Sensor for Combustible Gas
 
Sensitive material of MQ-7 gas sensor is SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). The sensors conductivity is more higher along with the gas concentration rising. When high temperature (heated by 5.0V), it cleans the other gases adsorbed under low temperature. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.

MQ-7 gas sensor has high sensitity to Carbon Monoxide. The sensor could be used to detect different gases contains CO, it is with low cost and suitable for different application.
 
Character :

1、High sensitivity to Combustible gas in wide range

2、High sensitivity to Natural gas 

3、Fast response

4、Wide detection range

5、Stable performance、long life、low cost    

6、Simple drive circuit 

Technical Data :


                                                                                          
Application :                     

1)  Domestic gas leakage detector

2)  Industrial CO detector

3)  Portable gas detector

Connecting Diagram :




This sensor module come with 3 Pin Dual-female Jumper Wire length 300mm as below :
