It can detect harmful gases such as ammonia, benzene, sulfides, smoke, and CO₂ with good sensitivity and fast response. The module provides both analog (0–5V) and digital outputs, with an adjustable threshold using a built-in potentiometer. It operates on 5V and requires a short warm-up time for stable readings. Suitable for home safety, environmental monitoring, and general air-quality detection.\u003c\/span\u003e\u003c\/p\u003e","brand":"FabLab","offers":[{"title":"Default Title","offer_id":50959595864379,"sku":"CPSEN005","price":1.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0950\/4509\/1643\/files\/CPSEN005-MQ-135-Gas-sensor.jpg?v=1770321029","url":"https:\/\/stablufablab.tech\/products\/mq-135-gas-and-air-quality-sensor","provider":"Stablu FabLab","version":"1.0","type":"link"}
