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 data-mce-fragment=\"1\"\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 data-mce-fragment=\"1\"\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 above.\u003c\/p\u003e","brand":"SparkFun","offers":[{"title":"Default Title","offer_id":44165663523065,"sku":"PL4M-SEN-22395","price":161.35,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/files\/E_7160fedc-a2fc-47fa-8bf5-19a61740bc52.jpg?v=1700859305","url":"https:\/\/getcahits.com\/es\/products\/sparkfun-co-humidity-and-temperature-sensor-scd40-qwiic","provider":"PuriLite","version":"1.0","type":"link"}
