Introduction
The Sensirion SGP40 delivers lab-quality volatile organic compound (VOC) monitoring in a compact 18mm package - providing immediate 0-500 air quality indexes without calibration.
Instant VOC Index Output
Generates ready-to-use 0-500 air quality scores (1-1000ppm ethanol equivalent) with built-in Sensirion algorithm - no complex calibration required.
Temperature-Compensated Accuracy
Integrated CMOSens® technology maintains ±15% accuracy across -10°C to 50°C environments with automatic humidity compensation.
Ultra-Fast 2-Second Response
Detects air quality changes faster than human perception - ideal for real-time ventilation control in kitchens, labs, and smart homes.
Industry-Leading Efficiency
Consumes just 2.6mA during operation - 60% less power than comparable VOC sensors for continuous IoT monitoring applications.
Note: VOC index is obtained by converting the detected ethanol equivalent in air.
