The Waveshare SGP40 module is a digital VOC (Volatile Organic Compounds) sensing solution based on Sensirion’s SGP40 metal-oxide (MOX) sensor. It employs a micro-hotplate structure for low-power operation and features integrated on-chip humidity and temperature compensation via a built-in SHT3x-A1 sensor, ensuring reliable VOC index readings independent of ambient conditions. The sensor outputs a digital VOC Index (VOC_Index) signal directly via the I2C interface.
Designed for integration into air quality monitoring systems, the module includes a level-shifting circuit, making it plug-and-play compatible with 3.3V and 5V logic families common in development platforms like Arduino, ESP32, Raspberry Pi, and STM32. Its compact PCB and low thermal footprint allow for deployment in confined spaces within air purifiers, smart HVAC systems, and indoor environmental monitors.
