Gravity: SGP40 Air Quality Sensor

1. Example Code for Arduino-Read VOC Index

Serial print the currect VOC index after the sensor is powered on for 10s. The chip has on-chip compensation, so users can use it without calibration. If you need to get a more accurate value, you can open the setrht() function and fill in the RH% of the ambient relative humidity value obtained by the external humidity detection sensor and the ° C of the ambient temperature detected by the temperature sensor.

2. Example Code for Raspberry Pi-Read VOC Index

This article details the process of setting up a Raspberry Pi with an SGP40 air quality sensor to read VOC index, including hardware requirements, software setup, wiring diagram, and Python code execution for effective air quality monitoring.
