簡介:
N-CH4煙霧氣體檢測模組,,是基于煙霧傳感器MQ-2設(shè)計而成,??梢灾苯舆B接單片機(jī)控制,。通過電位器,,用戶可以設(shè)定氣體報警濃度,,單片機(jī)可以通過模組高低電平信號檢測得到,。另外通過一路模擬電路輸出,,用戶還可以獲得當(dāng)前環(huán)境下,,具體的甲烷氣體濃度。
對液化氣,,天然氣,,城市煤氣,煙霧有較好的靈敏度,。具有長期的使用壽命和可靠的穩(wěn)定性,、快速的響應(yīng)恢復(fù)特性。
The N-CH4 Gas Sensor Module is designed to allow a microcontroller to determine when a preset Methane gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires two I/O pins from the host microcontroller. The sensor module is mainly intended to provide a means of comparing methane sources and being able to set an alarm limit when the source becomes excessive.
