SCD30 – CO2 & Temperature & Humidity Sensor

SCD30 – CO2 & Temperature & Humidity Sensor


The Grove – CO2 & Temperature & Humidity Sensor (SCD30) is a high precision carbon dioxide sensor, which is based on Sensirion SCD30. The measuring range of this sensor is 0 ppm-40’000 ppm, and the measurement accuracy can reach to ±(30 ppm + 3%) between 400ppm to 10’000ppm.

In addition to the Non-Dispersive Infrared (NDIR) measurement technology for CO2 detection, the SCD30 integrates Sensirion humidity and temperature sensors on the same sensor module.
