Gravity: Analog Gas Sensor MQ2 煙霧/氣體感測器 Arduino Sensor DFRobot原廠

Analog Gas Sensor 氣體傳感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。

Analog Gas Sensor  is based on the gas sensor MQ2 gas sensor, which can detect the smoke, liquefied gas, butane, propane, methane, alcohol, hydrogen and other gases in the air.
Used in conjunction with the Arduino dedicated sensor expansion board, it can produce fire smoke alarm, liquefied gas, butane, propane, methane, alcohol, hydrogen gas leak alarm and other related works.
The operating voltage is adapted to 3.3V and 5V. There is an uppercase A on the side of the port on the board, indicating that this is an analog sensor.
The small plate has a high-quality connector that can withstand tens of thousands of insertions and pulls to ensure a firm and good contact. The Shenjin process not only guarantees the performance of the module, but also has a golden luster.
