{"product_id":"mq-2-gas-detection-module","title":"MQ-2 Gas Detection Module","description":"\u003cp\u003eThe gas sensor is an electronic sensing module designed to respond to the presence or concentration changes of certain gases or vapors. It is suitable for Arduino, ESP32, robotics, automation, IoT, and STEM learning projects where a controller needs information about its surroundings or user interaction.\u003c\/p\u003e\n\u003cp\u003eThe module can typically be connected to a microcontroller using simple power and signal connections. Its output can be used to trigger LEDs, buzzers, relays, motors, displays, alarms, or software actions depending on the project. It is useful for both beginner experiments and practical prototypes.\u003c\/p\u003e\n\u003cp\u003eThis sensor provides a convenient way to add responsive, real-world input to electronic systems without building the sensing circuit completely from individual components.\u003c\/p\u003e\n\u003cp\u003eFeatures:\u003cbr\u003e• Detects changes in target gas concentration\u003cbr\u003e• Analog\/digital output on common modules\u003cbr\u003e• Adjustable sensitivity on typical module boards\u003cbr\u003e• Suitable for gas-leak and air-quality experiments\u003c\/p\u003e","brand":"OPSTA STORE","offers":[{"title":"Default Title","offer_id":55435403231551,"sku":null,"price":139.61,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/9111\/0463\/files\/gas-and-dust-sensor-2-1-768x768_jpg.webp?v=1788943151","url":"https:\/\/shop.opsta.in\/products\/mq-2-gas-detection-module","provider":"OPSTA STORE","version":"1.0","type":"link"}
