Indoor Air Quality Sensor With TVOC eCO2 And AQI Monitoring Using ENS160 Technology
The Indoor ENS160 Air Quality Sensor is a high-performance environmental monitoring module designed specifically for indoor air quality applications. Based on the advanced ScioSense ENS160 sensor chip, the module provides accurate measurement of Total Volatile Organic Compounds (TVOC), equivalent Carbon Dioxide (eCO2), and Air Quality Index (AQI). Combining innovative TrueVOC technology with Metal Oxide (MOX) sensing technology, the sensor delivers fast response times, high accuracy, and strong resistance to environmental interference.
The ENS160 features intelligent onboard processing that directly outputs meaningful air quality data without requiring complex calculations by the host controller. An automatic baseline correction algorithm continuously optimizes sensor performance, ensuring long-term measurement stability and reliability. With a simple I2C communication interface, the module can be easily integrated into Arduino, ESP32, Raspberry Pi, smart home systems, HVAC equipment, and IoT-based environmental monitoring applications.
