The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm.\u003c\/p\u003e  \n\n \u003cp\u003eThis 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.\u003c\/p\u003e  \n\n \u003cp\u003eThis sensor comes in a package similar to our MQ-3 alcohol sensor, and can be used with the breakout board below.\u003cbr\u003e\n \u003cbr\u003e\n -\u0026gt;\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39739989065909,"sku":"PL4-SEN-09404","price":26.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/09404-01.jpg?v=1618430351","url":"https:\/\/getcahits.com\/products\/pl4-sen-09404","provider":"PuriLite","version":"1.0","type":"link"}
