Air Quality Click is a simple solution for adding a high sensitivity sensor for detecting a variety of gases that impact air quality in homes and offices. It carries an MQ-135 sensor. The click is designed to run on a 5V power supply. It communicates with the target microcontroller over the AN pin on the mikroBUS™ line. Air Quality Click is suitable for detecting ammonia (NH3), nitrogen oxides (NOx) benzene, smoke, CO2 and other harmful or poisonous gases that impact air quality. The MQ-135 sensor unit has a sensor layer made of tin dioxide (SnO2), an inorganic compound which has lower conductivity in clean air than when polluting gases are present. To calibrate Air quality click for optimum performance, use the on-board potentiometer to adjust the load resistance on the sensor circuit.\u003c\/p\u003e\n\u003ch5\u003eAir Quality Click Features:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eMQ-135 sensor\u003c\/li\u003e\n\u003cli\u003eSnO2 gas sensing layer\u003c\/li\u003e\n\u003cli\u003eInterface: AN\u003c\/li\u003e\n\u003cli\u003e5V power supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eAir Quality Click Specifications:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eType: Gas,Air Quality\u003c\/li\u003e\n\u003cli\u003eApplications: Air quality detection for homes and offices\u003c\/li\u003e\n\u003cli\u003eOn-board modules: MQ-135 sensor\u003c\/li\u003e\n\u003cli\u003eCalibration:Potentiometer\u003c\/li\u003e\n\u003cli\u003eInterface: Analog\u003c\/li\u003e\n\u003cli\u003eCompatibility: mikroBUS\u003c\/li\u003e\n\u003cli\u003eClick board size: M (42.9 x 25.4 mm)\u003c\/li\u003e\n\u003cli\u003eInput Voltage: 3.3V, 5V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eResource Links\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.mikroe.com\/air-quality-click\/\" rel=\"noopener noreferrer\" target=\"_blank\"\u003eManufacturer’s product page\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":53397224096053,"sku":"64202","price":18.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1015\/6307\/2821\/files\/61811a2e-64202a.jpg?v=1787781829","url":"https:\/\/shop.parallax.com\/products\/air-quality-click","provider":"Parallax Inc","version":"1.0","type":"link"}
