{"product_id":"sparkfun-mikroe-air-quality-click","title":"SparkFun MIKROE Air Quality Click","description":"\u003cp\u003eMIKROE 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.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eDetecting gases\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eAir 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.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eCalibration potentiometer\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eTo calibrate Air quality Click for optimum performance, use the on-board potentiometer to adjust the load resistance on the sensor circuit.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eMQ-135 sensor \u003cul\u003e \u003cli\u003eSnO2 gas sensing layer\u003c\/li\u003e \u003c\/ul\u003e\n\u003c\/li\u003e \u003cli\u003eInterface: Analog\u003c\/li\u003e \u003cli\u003eDimensions: 42.9 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V, 5V\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUS�\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/3\/e\/9\/e\/0\/User_Manual-18929-Air_Quality_Click.pdf\"\u003eUser Manual\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/8\/0\/7\/7\/MQ135__Ver1.4__-_Manual.pdf\"\u003eMQ-135 Datasheet\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/github.com\/MikroElektronika\/mikrosdk_click_v2\/tree\/master\/clicks\/airquality\"\u003eGitHub\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eVideos\u003c\/strong\u003e\u003c\/p\u003e \u003cdiv class=\"flex-video-wrap clearfix\"\u003e \u003cdiv class=\"flex-video widescreen img\"\u003e \u003ciframe src=\"https:\/\/www.youtube.com\/embed\/zzlh1oGii1Q\/?autohide=1\u0026amp;border=0\u0026amp;wmode=opaque\u0026amp;enablejsapi=1\" frameborder=\"0\" allowfullscreen width=\"560\" height=\"315\"\u003e\u003c\/iframe\u003e \u003c\/div\u003e \u003c\/div\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40054693625941,"sku":"18929:SEN-18929:spark","price":2870.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/18929_-_Air_Quality_Click.jpg?v=1651343019","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-air-quality-click","provider":"Tanotis","version":"1.0","type":"link"}
