Grove SCD30 CO2 Temperature & Humidity Sensor for Arduino

The Grove SCD30 is a highly capable 3-in-1 environmental sensor module designed for seamless integration with Arduino projects, providing precise measurements of carbon dioxide (CO2) levels, temperature, and relative humidity. Based on the advanced Sensirion SCD30 sensor, it utilises Non-Dispersive Infrared (NDIR) technology for accurate CO2 detection, delivering readings within a precision of ±(30 ppm + 3%) across a wide range from 400ppm to 10,000ppm.

This multifunctional board is an ideal solution for developers and hobbyists looking to create sophisticated environmental monitoring systems without managing multiple discrete sensors. It integrates the CO2, temperature, and humidity sensing capabilities on a single, compact module, simplifying wiring and data fusion for applications such as indoor air quality monitors, smart greenhouse controllers, or personal weather stations.

Featuring a standard I2C digital interface, the sensor is both breadboard-friendly and fully compatible with the Grove ecosystem, allowing for plug-and-play connectivity with a wide range of microcontroller boards beyond Arduino. The dual-channel detection enhances measurement reliability. With its robust performance and integrated design, the Grove SCD30 empowers you to build comprehensive environmental projects with greater ease and accuracy.
