It is mainly used to detect \u003cstrong\u003eCarbon Monoxide\u003c\/strong\u003e. This sensor contains a sensing element, mainly aluminum-oxide based ceramic, coated with Tin dioxide (SnO\u003csub\u003e2\u003c\/sub\u003e), enclosed in a stainless-steel mesh. Whenever CO gas comes into contact with the sensing element, the resistivity of the element changes. The change is then measured to get the concentration of the gases present. The \u003cstrong\u003eMQ7 Sensor\u003c\/strong\u003e has a small heating element present which is needed to preheat the sensor to get it in the working window. It can detect \u003cstrong\u003eCarbon Monoxide Gas\u003c\/strong\u003e in the range of 20 PPM to 2000 PPM in the air. It finds uses in Alarm application in case of CO gas concentration build-up in the home or your car as CO is a very harmful gas and can kill a person if present over 300PPM.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Voltage is +5V\u003c\/li\u003e\n\u003cli\u003eCan be used to Measure or detect CO\u003c\/li\u003e\n\u003cli\u003eAnalog output voltage: 0V to 5V\u003c\/li\u003e\n\u003cli\u003eDigital Output Voltage: 0V or 5V\u003c\/li\u003e\n\u003cli\u003eStable, Long life and Low Cost\u003c\/li\u003e\n\u003cli\u003eFast Response time\u003c\/li\u003e\n\u003cli\u003eHeater consumption about 350mW\u003c\/li\u003e\n\u003cli\u003eThe Sensitivity of Digital Output pin can be varied using the potentiometer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg alt=\"Interface the MQ7 carbon mono-oxide(CO) Gas Sensor with Arduino -  ElectroVigyan\" decoding=\"async\" src=\"https:\/\/www.electrovigyan.com\/wp-content\/uploads\/2022\/03\/mq7-circuit-1-1200x628.jpg\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"NAT Electronics","offers":[{"title":"Default Title","offer_id":48270956069114,"sku":null,"price":2100.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/6993\/2794\/files\/MQ-7-1.jpg?v=1769860755","url":"https:\/\/natelectronics.pk\/products\/mq-7-gas-sensor-detecting-carbon-monoxide-gas","provider":"NAT Electronics","version":"1.0","type":"link"}
