Grove - CO2 & Temperature & Humidity Sensor (SCD30) 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.
CCS811 is a low-power digital gas sensor solution, which integrates a gas sensor solution for detecting low levels of VOCs typically found indoors, with a microcontroller unit (MCU) and an Analog-to-Digital converter to monitor the local environment and provide an indication of the indoor air quality via an equivalent CO2 or TVOC output over a standard I2C digital interface.

By knowing the exact concentration of CO2, we can do something to reduce the atmosphere's CO2 level and to protect our earth. For that reason, DFRobot eningeer's designed a high quality CO2 sensor. This is the first CO2 sensor on the opensource hardware market. The output voltage of the module falls as the concentration of the CO2 increases.
Jun 11, 2018· Introduction In this ESP32 tutorial, we will check how to get measurements from a C02 sensor, using the Arduino core. The sensor used was an Analog Infrared CO2 Sensor from DFRobot. You can find the Wiki page for the sensor here. Note that the code we are going to be developing here is based on the code available on the Wiki page of the product, which I encourage you to check.
