{"product_id":"pl4-sen-17049","title":"Smoke Sensor - MQ-2","description":"\u003cp\u003eThe MQ-2 is a smoke and combustible gas sensor from Winsen. It can detect flammable gas in a range of 300 - 10000ppm. It's most common use is domestic gas leakage alarms and detectors with a high sensitivity to propane and smoke. The sensing material is SNO‚‚ for which the conductivity is lower in clean environments and higher when smoke or flammable gas is present. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward, but does require some calibration.\u003c\/p\u003e \n\n\u003cp\u003eFor easy Solderability; use our [Gas Sensor Breakout Board](https:\/\/www.sparkfun.com\/products\/8891).\u003c\/p\u003e\n\n\u003cp\u003e**Documents:**\u003c\/p\u003e\n\n\u003cp\u003e* [Datasheet](https:\/\/cdn.sparkfun.com\/assets\/3\/b\/0\/6\/d\/MQ-2.pdf)\u003c\/p\u003e\n\n\u003cp\u003e**Videos**\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39740002861237,"sku":"PL4-SEN-17049","price":26.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/17049-Smoke_Sensor_-_MQ-2-02.jpg?v=1618430408","url":"https:\/\/getcahits.com\/products\/pl4-sen-17049","provider":"PuriLite","version":"1.0","type":"link"}
