Description:

The Waveshare SGP40 VOC Sensor is a compact digital sensor designed to detect volatile organic compounds (VOCs) and monitor air quality in real-time. Powered by the advanced SGP40 sensor chip, it accurately measures emissions from cigarettes, cooking smoke, natural gas, fire coal, construction materials, furniture, and home appliances. The sensor generates precise digital signals that can trigger air treatment devices for safer, cleaner environments. Its small form factor allows easy integration into air purifiers, air quality monitors, and smart home devices, making it an ideal choice for both practical applications and learning air quality monitoring.
