ENS160+AHT21 Carbon Dioxide, Air Quality, Temperature And Humidity Sensor CO2 eCO2 TVOC

The ENS160 + AHT21 is a powerful environmental sensing solution combining ScioSense’s ENS160 (IAQ – Indoor Air Quality Sensor) with ASAIR’s AHT21 (high-accuracy temperature and humidity sensor). This compact module provides real-time air quality data (TVOC, eCO2, AQI) along with precise temperature and humidity measurements, making it ideal for smart home devices, HVAC systems, IoT applications, and air purifiers.
