Mmm isn't it wonderful? All that air around us, which we bring into our lungs, extracts oxygen from, and then breathe out carbon dioxide. CO2 is essential for life on this planet we call Earth - we and plants take turns using and emitting CO2 in an elegant symbiosis. But it's important to keep that CO2 balanced - you don't want too much around, not good for humans and not good for our planet.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"\/en-eu\/products\/adafruit-sgp30-air-quality-sensor-breakout-voc-and-eco2\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eUnlike the SGP30, this sensor isn't approximating it from VOC gas concentration\u003c\/a\u003e - \u003cstrong\u003eit really is measuring the CO2 concentration!\u003c\/strong\u003e That means it's a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more.\u003c\/p\u003e\n\u003cp\u003eData is read over I2C, so it works very nicely with just about any microcontroller or microcomputer. Adafruit have written both Arduino and Python\/CircuitPython code so you can get started in a jiffy. Another nice element to this sensor is it comes with an \u003ca href=\"\/en-eu\/products\/adafruit-sensiron-sht31-d-temperature-humidity-sensor-breakout\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eSHT31 temperature and humidity sensor\u003c\/a\u003e already built-in. The sensor is used to compensate the NDIR CO2 sensor, but it's also readable so you get full environmental data.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSCD-30 Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNDIR CO2 sensor technology\u003c\/li\u003e\n\u003cli\u003eIntegrated temperature and humidity sensor\u003c\/li\u003e\n\u003cli\u003eDual-channel detection for superior stability\u003c\/li\u003e\n\u003cli\u003eMeasurement range: 400 ppm – 10.000 ppm\u003c\/li\u003e\n\u003cli\u003eAccuracy: ±(30 ppm + 3%)\u003c\/li\u003e\n\u003cli\u003eCurrent consumption: 19 mA @ 1 meas. per 2 s.\u003c\/li\u003e\n\u003cli\u003eFully calibrated and linearized\u003c\/li\u003e\n\u003cli\u003eI2C digital interface address 0x61\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNice sensor right?
