商品說明

Gravity: Analog Gas Sensor MQ2 煙霧/氣體感測器 產品介紹

Analog Gas Sensor 氣體感測器是基於氣敏元件的 MQ2 氣體 感測器，可以很靈敏的檢測到空氣中的煙霧、液化氣、丁烷、丙烷、甲烷、酒精、氫氣等氣體。

與Arduino專用傳感器擴展板結合使用，可以製作火災煙霧報警、液化氣、丁烷、丙烷、甲烷、酒精、氫氣氣體洩露報警等相關的作品。

運行電壓適應3.3V和5V供電。小板上的端口邊上有一個大寫的A，標明這是一個模擬的傳感器。

小板上帶有高品質接頭，能夠經受上萬次插拔，保證接觸牢固，良好。沈金工藝，不僅保證模塊的性能，而且帶有金色光澤。

Gravity: Analog Gas Sensor (MQ2) For Arduino

This is a generic Arduino gas sensor. It has MQ2 probe which is able to detect LPG, i-butane, propane, methane ,alcohol, Hydrogen, smoke.
It can be used in gas leakage detecting device in consumer and industry markets. It has a high sensitivity and fast response time.
The sensitivity can be adjusted by the potentiometer. The output is proportional to the density of gas. You can use analog reading to read the data from this sensor.
To ease the difficulty of using this sensor,  a Gravity Interface is adapted to allow plug&play.  The Arduino IO expansion shield is the best match for this senor connecting to your Arduino. As this sensor can work at 3.3V which makes it compatible with Raspberry Pi, intel edison, joule and curie.
