{"product_id":"mq3-alcohol-ethanol-sensor","title":"MQ3 Alcohol Ethanol Sensor","description":"\u003cp\u003eThis is the MQ-3 Gas Sensor Module, which is simple to use. It can sense the presence of Alcohol in the air. The module uses our MQ-3 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides an interface through standard 4 x 0.1? header pins.  MQ-3 gas sensor provides an analog output corresponding to the concentration of the gas in the air and an easy-to-use digital output.\u003c\/p\u003e\n\u003cp\u003eThe sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air. Its conductivity increases as the concentration of alcohol gasses increases. It has a high sensitivity to alcohol and has good resistance to disturbances due to smoke, vapour and gasoline. MQ-3 gas sensor module provides both digital and analog outputs. It can be easily interfaced with Microcontrollers like Arduino Boards and Raspberry pi\u003c\/p\u003e\n\u003cp\u003eThis MQ-3 alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breath analyser. It has a high sensitivity and fast response time. The sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC\u003c\/p\u003e","brand":"OPSTA STORE","offers":[{"title":"Default Title","offer_id":55694741078335,"sku":null,"price":173.07,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/9111\/0463\/files\/images_4.jpg?v=1790155742","url":"https:\/\/shop.opsta.in\/products\/mq3-alcohol-ethanol-sensor","provider":"OPSTA STORE","version":"1.0","type":"link"}
