The heated metal oxide changes resistance based on the volatile organic compounds (VOC) in the air, so it can be used to detect gasses \u0026amp; alcohols such as Ethanol, Alcohol and Carbon Monoxide, and perform air quality measurements. Note it will give you one resistance value, with overall VOC content, but it cannot differentiate gasses or alcohols.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note this sensor, like \u003cem\u003eall\u003c\/em\u003e VOC\/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources!\u003c\/strong\u003e That said, for general environmental sensors, it will give you a good idea of trends and comparisons. We recommend that you run this sensor for 48 hours when you first receive it to \"burn it in\", and then 30 minutes in the desired mode every time the sensor is in use. This is because the sensitivity levels of the sensor will change during early use, and the resistance will slowly rise over time as the MOX warms up to its baseline reading.\u003c\/p\u003e\n\u003cp\u003eFor your convenience we've pick-and-placed the sensor on a PCB with a 3.3V regulator and some level shifting, so it can be easily used with your favorite 3.3V or 5V microcontroller.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-bme680-humidity-temperature-barometic-pressure-voc-gas\/\"\u003eThis detailed tutorial will get you going with code for both \u003cstrong\u003eArduino\u003c\/strong\u003e and \u003cstrong\u003eCircuitPython\u003c\/strong\u003e, schematics, wiring diagrams, Fritzing objects and more!\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Dimensions: 18.0mm x 16.5mm x 2.8mm \/ 0.7\" x 0.6\" x 0.1\"\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 3.0g \/ 0.1oz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul id=\"product-files\"\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/product-files\/3660\/BME680.pdf\"\u003eBME680 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":42291036651711,"sku":"MLE00818","price":1550.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/sg-11134201-7rd5m-lve59rcnkyccb0.jpg?v=1735815712","url":"https:\/\/makerlab.ph\/products\/adafruit-bme680-temperature-humidity-pressure-and-gas-sensor","provider":"Makerlab PH","version":"1.0","type":"link"}
