DESCRIPTION
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.
FEATURES
ENS160 Air Quality Sensor
- Measures TVOC (Total Volatile Organic Compounds), eCO2 (Equivalent CO2), and Air Quality Index (AQI)
- MOX (Metal-Oxide) Gas Sensor with superior accuracy
- I²C & SPI interfaces for easy integration
- Ultra-low power consumption for battery-operated devices
- On-chip algorithm for real-time IAQ assessment
AHT21 Temperature & Humidity Sensor
- ±0.3°C temperature accuracy
- ±2% RH humidity accuracy
- Wide operating range: -40°C to +85°C
- Fully calibrated & digital output (I2C)
- Low power consumption (ideal for IoT & wearables)
APPLICATIONS
- Smart thermostats & HVAC systems
- Air purifiers & ventilation control
- Home automation & IoT devices
- Wearable health & wellness monitors
