Product Description

Electronic Brick - MQ - 2 Gas Sensor Brick
Electronic Brick - MQ - 2 Gas Sensor Brick

What is an electronic brick?

1. An electronic brick is an electronic module which can be assembled like Lego bricks simply by plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various needs of different projects.
2. The electronic brick of gas sensor can be used in fire protection systems to detect hydrogen, isobutane, liquefied petroleum gas, methane, carbon monoxide, alcohol, smoke, propane and other harmful gases.

MQ - 2 Gas Sensor Brick Features:
 
1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.
2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.
