This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.\u003c\/p\u003e\n\u003cdiv class=\"row-fluid build-text\"\u003e\n\u003cp\u003eThis is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row-fluid build-text\"\u003e\n\u003cp\u003eThe SGP30 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row-fluid build-text\"\u003e\n\u003cp\u003eThis part will measure \u003cstrong\u003eeCO2\u003c\/strong\u003e (equivalent calculated carbon-dioxide) concentration within a range of 0 to 60,000 parts per million (ppm), and \u003cstrong\u003eTVOC\u003c\/strong\u003e (Total Volatile Organic Compound) concentration within a range of 0 to 60,000 parts per billion (ppb).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note, this sensor, like all 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 comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"row-fluid build-text\"\u003e\n\u003cp\u003eAnother nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC\/eCO2 values.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUses I2C address 0x58\u003c\/li\u003e\n\u003cli\u003eProduct Dimensions: 17.9mm x 17.9mm x 2.9mm \/ 0.7\" x 0.7\" x 0.1\"\u003c\/li\u003e\n\u003cli\u003eProduct Weight: 1.1g \/ 0.0oz\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCode: 3709\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-sgp30-gas-tvoc-eco2-mox-sensor\/\"\u003eSoftware libraries, hookup guide, datasheets, schematic, EagleCAD PCB files, and Fritzing available in the product tutorial!\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n\u003cstrong\u003ePacking List:\u003cbr\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x SGP30 Air Quality Sensor Breakout\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eheader pins\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":42291005456575,"sku":"MLE00515","price":1550.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/MLE00515.jpg?v=1755825786","url":"https:\/\/makerlab.ph\/products\/adafruit-sgp30-air-quality-sensor-breakout-voc-eco2","provider":"Makerlab PH","version":"1.0","type":"link"}
