This sensing element is subjected to current through connecting leads. This current is known as heating current through it, the gases coming close to the sensing element get ionized and are absorbed by the sensing element. This changes the resistance of the sensing element which alters the value of the current going out of it.\u003c\/div\u003eThe MQ 135 Gas Sensor is a highly sensitive air quality sensor designed to detect ammonia (NH3), sulfur dioxide (SO2), benzene, smoke, carbon dioxide (CO2), and other harmful gases. It is widely used in air quality monitoring systems, gas leak detection, and environmental pollution measurement.\u003cbr\u003e\u003cbr\u003eWith both analog and digital outputs, the MQ-135 sensor can be easily interfaced with Arduino, Raspberry Pi, ESP32, and other microcontrollers, making it ideal for IoT-based air quality projects.\u003c\/div\u003e\u003chr\u003e\u003ch3\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 5V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetectable Gases:\u003c\/strong\u003e Ammonia (NH3), Carbon Dioxide (CO2), Benzene, Smoke, Alcohol, Acetone, and other harmful gases\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDetection Range:\u003c\/strong\u003e 10 ppm – 1000 ppm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput:\u003c\/strong\u003e Analog \u0026amp; Digital\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreheat Time:\u003c\/strong\u003e ≥ 20 seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResponse Time:\u003c\/strong\u003e ≤ 30 seconds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e -10°C to 50°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e ≤ 150mA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Robostan.pk","offers":[{"title":"Default Title","offer_id":54648105206126,"sku":null,"price":225.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/7391\/8062\/files\/mq-135-air-quality-sensor-1.jpg?v=1787673040","url":"https:\/\/robostan.pk\/products\/mq-135","provider":"ROBOSTAN","version":"1.0","type":"link"}
