The SCD30 is a 3-in-1 sensor that is capable of measuring CO2 levels, temperature, and humidity. Built on the reliable Sensirion SCD30, it uses non-dispersive Infrared (NDIR) technology to provide high-precision CO2 measurements, with an impressive accuracy of ±(30 ppm + 3%) for concentrations ranging from 400 ppm to 10,000 ppm. It is compatible with Arduino (With a Grove - Base Shield) and Raspberry Pi (Only with the Grove-Base HAT) If you're looking for more than just a simple temperature or CO2 sensor, this multifunctional sensor is a fantastic option for creating an Arduino weather station or other environmental projects.
