    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

    • Item #: 9SIVUX4M945278
    • Mfr. Part #: 623354876982
    • 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.

    Product Description:

    ENS160+AHT21 air quality sensor module for monitoring eCO2, TVOC, AQI, ambient temperature, and relative humidity. This compact module combines gas sensing and temperature-humidity detection for smart home, HVAC, air purifier, indoor environmental monitoring, and IoT projects.

    Core Selling Points:

    The integrated ENS160 gas sensor uses MOX metal-oxide sensing technology and a built-in algorithm for indoor air quality evaluation. The AHT21 temperature-humidity sensor supplies environmental compensation to help reduce measurement drift caused by ambient temperature and humidity changes. Supports simultaneous output of multiple environmental parameters. Low-power design supports battery-powered IoT terminal hardware, while clear pin markings simplify wiring and secondary development.
