This sensor board can provide a variety of environmental data, including barometric pressure, humidity, temperature, equivalent TVOCs and equivalent CO2 (or eCO2) levels.\u003c\/p\u003e\n\u003cp\u003eThe gator:environment connects to the \u003ca href=\"\/en-eu\/products\/sparkfun-gator-bit\" target=\"_blank\"\u003eSparkFun gator:bit\u003c\/a\u003e via alligator-clip cables, allowing for easy access to the micro:bit's I\u003csup\u003e2\u003c\/sup\u003eC pins.\u003c\/p\u003e\n\u003cp\u003eThe CCS811 is a digital metal oxide (MOX) gas sensor that detects wide range of Volatile Organic Compounds (VOCs). With an integrated microcontroller that implements special algorithms to process the raw measurements, the CCS811 outputs the equivalent total VOC (eTVOC) and equivalent CO\u003csub\u003e2\u003c\/sub\u003e (eCO\u003csub\u003e2\u003c\/sub\u003e) values over an I\u003csup\u003e2\u003c\/sup\u003eC connection. It provides readings for the total volatile organic compounds in the parts per billion (PPB) and equivalent CO\u003csub\u003e2\u003c\/sub\u003e (or eCO\u003csub\u003e2\u003c\/sub\u003e) in the parts per million (PPM). It also has a feature that allows it to fine tune its readings if it has access to the current humidity and temperature. Luckily for us, the BME280 provides humidity, temperature, and barometric pressure! This allows the sensors to work together to give us more accurate readings than they'd be able to provide on their own.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNote:\u003c\/b\u003e Unfortunately, CO\u003csub\u003e2\u003c\/sub\u003e isn't a VOC and MOX type of sensors can't directly measure CO\u003csub\u003e2\u003c\/sub\u003e, despite being great at VOC detection. However, in an indoor setting, humans are a primary source of VOCs through the process of breathing. The equivalent CO\u003csub\u003e2\u003c\/sub\u003e (eCO\u003csub\u003e2\u003c\/sub\u003e) values are then estimated based on algorithms that are used to analyze the sensor data to determine the TVOC attributed by the presence of humans. This type of sensor should not be used in applications that directly require the measurement of CO\u003csub\u003e2\u003c\/sub\u003e; it is an \u003cu\u003einferred value\u003c\/u\u003e.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003egator:bit Compatible\u003c\/li\u003e\n\u003cli\u003eCCS811\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 1.8V-3.6V\u003c\/li\u003e\n\u003cli\u003eSupply Current: 30 mA (average)\u003c\/li\u003e\n\u003cli\u003eEquivalent Total VOCs (eTVOC): 0-32768 ppb\u003c\/li\u003e\n\u003cli\u003eEquivalent CO\u003csub\u003e2\u003c\/sub\u003e (eCO\u003csub\u003e2\u003c\/sub\u003e): 400-29206 ppm\u003c\/li\u003e\n\u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC Address: 0x5B (HEX)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eBME280\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 1.71V-3.6V\u003c\/li\u003e\n\u003cli\u003eSupply Current: \u0026lt; 714 µA\u003c\/li\u003e\n\u003cli\u003eHumidity Range: 0 to 100% RH\u003c\/li\u003e\n\u003cli\u003eTemperature Range: -40°C to 85°C\u003c\/li\u003e\n\u003cli\u003ePressure Range: 300 to 1100 hPa\u003c\/li\u003e\n\u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC Address: 0x77 (HEX)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn2.shopify.com\/s\/files\/1\/0174\/1800\/files\/gator_environment_Schematic.pdf?21015\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/d\/f\/e\/c\/e\/gator_environment.zip\" target=\"_blank\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-gatorenvironment-hookup-guide\" target=\"_blank\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/6\/4\/c\/6\/7\/BME280_Datasheet.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e (BME280)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/2\/4\/2\/9\/6\/CCS811_Datasheet.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e (CCS811)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/5\/2\/1\/8\/4\/CCS811_Design_Guidelines.pdf\" target=\"_blank\"\u003eDesign Guide\u003c\/a\u003e (CCS811)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/d\/d\/3\/8\/b\/CCS811_Factsheet.pdf\" target=\"_blank\"\u003eFactsheet\u003c\/a\u003e (CCS811)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/pxt-gator-environment\" target=\"_blank\"\u003egator:environment PXT Package\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/gator_environment\" target=\"_blank\"\u003eGitHub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":29402005438547,"sku":"SEN-15269","price":24.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/15269-SparkFun_gator-environment_-_micro-bit_Accessory_Board-01.jpg?v=1563207870","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/sparkfun-gator-environment-micro-bit-accessory-board","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
