This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm.

This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

This sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.

這是一個簡單使用的壓縮天然氣(CNG)的傳感器,適於感測天然氣在空氣中的濃度(主要是甲烷[CH 4]組成)。在MQ-4可以檢測天然氣濃度從200到任何地方10000PPM。

這個傳感器具有高的靈敏度和快速響應時間。傳感器的輸出是一個模擬的電阻。驅動電路非常簡單;所有你需要做的是功率5V加熱線圈,加負載電阻,輸出連接到ADC。

該傳感器來以類似於我們的MQ-3醇傳感器的封裝,並可以與下面的轉接板一起使用。
