ENS160+AHT21 Indoor Air Quality Sensor Module with I2C/SPI Digital Output eCO2 TVOC AQI Temperature Humidity Detection Gas and Environmental Monitoring Board for Smart Home HVAC IoT
- Integrated module combines an ENS160 indoor air quality chip with an AHT21 temperature and humidity sensor on one compact circuit board.
- Detects equivalent carbon dioxide (eCO2), total volatile organic compounds (TVOC), AQI, ambient temperature, and relative humidity.
- ENS160 uses MOX metal-oxide gas sensing technology and supports both I2C and SPI digital communication interfaces.
- Built-in processing algorithm provides gas-data output for indoor air quality evaluation and environmental monitoring applications.
- AHT21 temperature and humidity readings provide environmental compensation to help reduce gas-sensor drift from ambient fluctuations.
- Low-power design supports battery-driven IoT terminal hardware requiring multiple environmental parameter measurements.
- Clear pin markings simplify wiring; compatible with Raspberry Pi for data reading and project integration.
- Allow a warm-up period after power-on for stable measurement data, and install the corresponding driver library for normal reading.
