It also reports temperature and humidity, making it a good core for ventilation monitors, air-quality displays and science experiments.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eReal CO2 measurement in parts per million (ppm)\u003c\/li\u003e\n\u003cli\u003eTemperature and humidity readings from the same sensor\u003c\/li\u003e\n\u003cli\u003eMuch smaller than the SCD-30 thanks to a different measurement technique, with similar data quality\u003c\/li\u003e\n\u003cli\u003eI2C interface with STEMMA QT \/ Qwiic connectors\u003c\/li\u003e\n\u003cli\u003eArduino and Python\/CircuitPython code available to get started\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor:\u003c\/strong\u003e Sensirion SCD-40, photoacoustic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCO2 range:\u003c\/strong\u003e 400–2000 ppm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso measures:\u003c\/strong\u003e Temperature, humidity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterface:\u003c\/strong\u003e I2C, 3–5 V\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWorks with\u003c\/h3\u003e\u003cp\u003eArduino, Raspberry Pi, CircuitPython and ESP32.\u003c\/p\u003e\u003cp\u003eFind more air-quality sensors in our \u003ca href=\"\/collections\/sensors-modules\"\u003esensors and modules collection\u003c\/a\u003e.\u003c\/p\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":67994099843177,"sku":"ADA5187","price":44.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0265\/1537\/4185\/files\/5187-04.jpg?v=1794001368","url":"https:\/\/makersthings.com\/products\/adafruit-adafruit-scd-40-true-co2-temperature-and-humidity-sensor","provider":"maker's things","version":"1.0","type":"link"}
