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 ppm40''000 ppm, and the measurement accuracy can reach to ± (30 ppm + 3%) between 400ppm to 10''000ppm.
· According to the datasheet I found, the sensor has a UART interface, so a level converter to 3V3 should be enough if you want to access just one these sensors. As the sensor uses a baud rate of 9600 you should use an Arduino that has a hardware serial interface to connect the sensor. So if you want to have your PC connected while reading the sensor, use a MegaXXXX model or a Leonardo.
