Electronic Brick 

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.

 Overview 

This MQ-2 sensor brick includes a MQ-2 Gas sensor. Gas Sensor(MQ2) module is useful for detecting gas leakage ( home and industry). It is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, somke and so on. Based on its fast response time. measurements can be taken as soon as possible.

Connect the + pin to 5v and - pin to GND, S pin will output the analog value which is concentration-related. It can be used with Iteaduino directly with a 3PIN cable.

 

 Programming

Connect the module with Iteaduino using A0. Use the program below to gain the voltage. You can see the voltage will go higher if the concentration of the gas increments.
