{"product_id":"sparkfun-co-humidity-and-temperature-sensor-scd40-qwiic","title":"SparkFun CO₂ Humidity and Temperature Sensor - SCD40 (Qwiic)","description":"\u003cp\u003eThis SparkFun CO2 Humidity and Temperature Sensor features the next-generation \u003cstrong\u003eSCD40\u003c\/strong\u003e photoacoustic CO2 sensor for high-accuracy environmental readings. The SCD40 uses Sensirion's PASens® photoacoustic measurement system that combines narrow-band IR light and a microphone inside the sensing package capable of detecting concentrations from 0 to 40000 ppm with high accuracy over 400-2000 ppm ±(50 ppm+5%).\u003c\/p\u003e\n\u003cp\u003eThe SCD40 has an integrated temperature and humidity CMos® sensor to improve accuracy. For additional accuracy, the SCD40 also accepts ambient pressure readings! All this functionality comes in our standard 1in. x 1in. Qwiic form factor and will seamlessly integrate into your Qwiic-based projects. However, we still routed the I2C signals out to a set of 0.1in.-spaced pins for users who prefer a soldered connection.\u003c\/p\u003e\n\u003cp\u003eThe SCD40 includes an automatic self-calibration routine to automatically adjust to its sensing environment over a seven-day calibration period. For best results, Sensirion recommends taking continuous readings for at least one hour a day of 'fresh air' for the calibration period to complete.\u003c\/p\u003e\n\u003cp\u003eWe've written an Arduino library to make reading the CO₂, humidity, and temperature very easy. It can be downloaded through the Arduino Library manager: search for 'SparkFun SCD4x', or it can be found in the Documents tab below.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Qwiic_CO2_Sensor_SCD4X\/introduction\/\"\u003eGet started with the Sparkfun SCD4X CO2 hookup guide\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/sJqToow_iAg?start=54\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eI2C Interface (Qwiic-enabled)\n\u003cul\u003e\n\u003cli\u003eI2C Address: 0x62\u003c\/li\u003e\n\u003cli\u003e2x Qwiic Connectors\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSupply Voltage Range: 2.4-5.5V (3.3V Typ.)\u003c\/li\u003e\n\u003cli\u003eLow Current Consumption:\n\u003cul\u003e\n\u003cli\u003eNormal Mode:\n\u003cul\u003e\n\u003cli\u003eMax: 205mA@3.3V\u003c\/li\u003e\n\u003cli\u003eTyp: 18mA@3.3V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eLow Power Mode:\n\u003cul\u003e\n\u003cli\u003eTyp: 3.5mA@3.3V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSingle-Shot:\n\u003cul\u003e\n\u003cli\u003e0.5mA@3.3V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003ePhotoacoustic Measurement System\n\u003cul\u003e\n\u003cli\u003eSensirion's PASens Technology\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eIntegrated Temperature and Humidity Sensor\n\u003cul\u003e\n\u003cli\u003eSensirion's CMOSens Technology\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eCO2 Output Range: 0-40,000ppm\u003c\/li\u003e\n\u003cli\u003eCO2 Measurement Accuracy: ±(50ppm + 5% of reading)\n\u003cul\u003e\n\u003cli\u003eConditions: 400-2,000ppm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eHumidity Range: 0-100%RH\u003c\/li\u003e\n\u003cli\u003eHumidity Accuracy: ±9%RH (Full Range)\u003c\/li\u003e\n\u003cli\u003eTemperature Range: -10°C-60°C\u003c\/li\u003e\n\u003cli\u003eTemperature Accuracy: ±1.5 (Full Range)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/9\/b\/f\/5\/2\/SparkFun_Qwiic_CO2_Sensor_SCD40.pdf?_gl=1*32nlwg*_ga*NDYwMjM5MTMxLjE2NzIyNDIzODQ.*_ga_T369JS7J9N*MTY4ODU2MDU4Ni4yLjAuMTY4ODU2MDU4Ni4wLjAuMA..\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/7\/3\/4\/5\/c\/SparkFun_Qwiic_CO2_Sensor_SCD40.zip\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/3\/d\/2\/c\/1\/SparkFun_Qwiic_CO2_Sensor_SCD4x-Dimensions.png\"\u003eBoard Dimensions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sparkfun.github.io\/SparkFun_Qwiic_CO2_Sensor_SCD4X\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/d\/4\/9\/a\/d\/Sensirion_CO2_Sensors_SCD4x_Datasheet.pdf\"\u003eDatasheet\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003e(SCD4X)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003eQwiic Information Page\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_SCD4x_Arduino_Library\"\u003eSCD4X Arduino Library\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Qwiic_CO2_Sensor_SCD4X\"\u003eGithub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":50847633015057,"sku":"SEN-22395","price":56.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/sparkfun-co-humidity-and-temperature-sensor-scd40-qwiic-sparkfun-sen-22395-40650087334083.jpg?v=1735216998","url":"https:\/\/abcd3032.myshopify.com\/products\/sparkfun-co-humidity-and-temperature-sensor-scd40-qwiic","provider":"Tayyab Zak","version":"1.0","type":"link"}
