MQ-2傳感器簡介:
MQ-2氣體傳感器所使用的氣敏材料是在清潔空氣中電導率較低的二氧化錫(SnO2)。當傳感器所處環境中存在可燃氣體時,傳感器的電導率隨空氣中可燃氣體濃度的增加而增大。
使用簡單的電路即可將電導率的變化轉換為與該氣體濃度相對應的輸出信號。 MQ-2氣體傳感器對液化氣、丙烷、氫氣的靈敏度高,對天然氣和其它可燃蒸汽的檢測也很理想。這種傳感器可檢測多種可燃性氣體,是一款適合多種應用的低成本傳感器。
模塊應用:
可以用於家庭和工廠的氣體泄漏監測裝置,適宜於液化氣、丁烷、丙烷、甲烷、煙霧等的探測;
模塊特色:
1、採用優質雙面板設計,具有電源指示和TTL信號輸出指示;
2、具有DO開關信號(TTL)輸出和AO模擬信號輸出;
3、TTL輸出有效信號為低電平。(當輸出低電平時信號燈亮,可直接接單片機或繼電器模塊)
4、模擬量輸出電壓隨濃度越高電壓越高。
5、對液化氣,天然氣,城市煤氣,煙霧有較好的靈敏度。
6、有四個螺絲孔便於定位;
7、產品外形尺寸:32(L)*20(W)*22(H)
8、具有長期的使用壽命和可靠的穩定性
9、快速的響應恢復特性
電氣性能:
輸入電壓:DC5V 功耗(電流):150mA
DO輸出:TTL數字量0和1(0.1和5V)
AO輸出:0.1-0.3V(相對無污染),最高濃度電壓4V左右
特別提醒:傳感器通電後,需要預熱20S左右,測量的數據才穩定,傳感器發熱屬於正常現象,因為內部有電熱絲,如果燙手就不正常了。
接線方式:
1、VCC:接電源正極(5V)
2、GND:接電源負極
3、DO:TTL開關信號輸出
4、AO:模擬信號輸出
