AJMRTC ENS160+AHT21 composite air quality sensor module integrates ENS160 indoor air quality chip and AHT21 highprecision temperaturehumidity sensor on one compact circuit board. It can collect multiple groups of environmental parameters at the same time, including equivalent carbon dioxide eCO2, total volatile organic compounds TVOC, AQI air quality index, ambient temperature and relative humidity. The ENS160 supports I2C and SPI communication modes, with builtin processing algorithm to realize reliable gasdata output. The matched AHT21 provides accurate temperaturehumidity data, which is used for algorithm compensation to effectively restrain sensor drift caused by temperature and humidity fluctuation. Lowpower characteristic makes it fit for batterydriven IoT terminal hardware. Clear pin marking simplifies wiring for Arduino, Raspberry Pi and other main controllers. It is ideal for smarthome equipment transformation, airpurifier monitoring, HVAC system auxiliary detection, indoor environmentalmonitoring DIY projects. Please complete warmup after poweron for stable measuring data, and match correct driver library for normal data reading.
