This repository contains the Python driver to communicate with Sensirion VOC sensor SGP40 and VOC/NOx sensor SGP41 using the I²C interface. For details, please read the user manual.
- SGP40
- SGP41
The User Manual explains how to install the driver and documents it's API.
It also includes a Quick-Start Guide that shows how to execute first measurments using the included examples.
After each restart of the SGP41 sensor or when the hotplates have been switched off, the conditioning command must be called from idle mode. The conditioning heats the hotplate of the NOx pixel to a different temperature compared to the measurement mode enabling a faster switch-on thereafter.
It is recommended to execute the conditioning for 10s, but 10s must not be exceeded to avoid damage to the sensing material.
