{"product_id":"scd41-co2-sensor-breakout","title":"SCD41 CO2 Sensor Breakout (Carbon Dioxide \/ Temperature \/ Humidity)","description":"\u003cp\u003eA true carbon dioxide sensor that can detect CO2 levels between 400 and 5,000 ppm, mounted on a Breakout Garden and Qw\/ST-compatible breakout.\u003c\/p\u003e\n\u003cp\u003eSCD41 is a high accuracy sensor that uses \u003cstrong\u003ephotoacoustic technology\u003c\/strong\u003e to tell you the precise proportion of \u003cstrong\u003ecarbon dioxide\u003c\/strong\u003e (in ppm) of the air that you're breathing. It can also measure \u003cstrong\u003etemperature and relative humidity.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eToo much carbon dioxide has all sorts of unpleasant effects on humans, such as turning up your tiredness levels and turning down your brain power. CO2 build-up is a useful indicator of \u003cstrong\u003ehow well ventilated a space is\u003c\/strong\u003e and also how many people are breathing the same air - a variable that's definitely worth tracking in homes, workplaces and schools at the moment. SCD41 is the \u003cstrong\u003eextended range\u003c\/strong\u003e variant of this sensor which means it can detect very high levels of CO2 at up to 5,000 ppm, so it could potentially also be useful in industrial and laboratory settings.\u003c\/p\u003e\n\u003cp\u003eWe've been testing out this sensor in some of the more confined scuppers and bilges of Pimoroni HQ, and it's remarkable how sensitive it is - you can really see the change in CO2 levels when someone enters or leaves a room, or when doors are open or closed.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis breakout is compatible with our fancy \u003c\/span\u003e\u003ca href=\"\/en-eu\/collections\/breakout-garden\" data-mce-href=\"\/en-eu\/collections\/breakout-garden\" target=\"_blank\"\u003eBreakout Garden\u003c\/a\u003e\u003cspan\u003e system, where using breakouts is as easy just popping it into one of the slots and starting to grow your project, create, and code. \u003c\/span\u003e\u003cspan\u003eIt's also\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eQw\/ST compatible\u003c\/strong\u003e\u003cspan\u003e so it can be plugged into a whole range of different \u003c\/span\u003e\u003ca href=\"https:\/\/shop.pimoroni.com\/collections\/stemma-qt\" target=\"_blank\" data-mce-href=\"https:\/\/shop.pimoroni.com\/collections\/stemma-qt\"\u003emicrocontrollers and HATs\u003c\/a\u003e\u003cspan\u003e with Qwiic or STEMMA QT connectors.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSensiron SCD41 carbon dioxide sensor (\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/Sensirion_CO2_Sensors_SCD4x_Datasheet.pdf?v=1642503159\" target=\"_blank\"\u003edatasheet\u003c\/a\u003e)\u003c\/li\u003e\n\u003cul\u003e\n\u003cli\u003ePhotoacoustic sensor technology PASens®\u003c\/li\u003e\n\u003cli\u003eHigh accuracy: ±(40 ppm + 5 %)\u003c\/li\u003e\n\u003cli\u003eRange: 400 ppm – 5,000 ppm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003eI2C interface, with address: 0x62\u003c\/li\u003e\n\u003cli\u003eQwiic\/STEMMA QT connector\u003c\/li\u003e\n\u003cli\u003e3-5V compatible\u003c\/li\u003e\n\u003cli\u003eReverse polarity protection (on Breakout Garden connector)\u003c\/li\u003e\n\u003cli\u003eRaspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)\u003c\/li\u003e\n\u003cli\u003eCompatible with Raspberry Pi (\u003ca href=\"https:\/\/github.com\/pimoroni\/scd4x-python\" data-mce-href=\"https:\/\/github.com\/pimoroni\/scd4x-python\" target=\"_blank\"\u003ePython library\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003eCompatible with Raspberry Pi Pico (\u003ca href=\"https:\/\/github.com\/pimoroni\/pimoroni-pico\" target=\"_blank\" data-mce-href=\"https:\/\/github.com\/pimoroni\/pimoroni-pico\"\u003eC++\/MicroPython libraries\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/scd41_breakout_schematic.pdf?v=1643203877\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eKit includes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSCD41 breakout\u003c\/li\u003e\n\u003cli\u003e1x5 male header\u003c\/li\u003e\n\u003cli\u003e1x5 female right angle header\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe've designed this breakout board so that you can solder on the piece of right angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).
