The module integrates two high-performance digital sensors: the AHT20 for temperature and relative humidity, and the BMP280 for barometric pressure and altitude estimation. Both sensors provide calibrated, stable digital outputs via a shared I2C bus, simplifying system wiring and firmware development. The AHT20 utilizes a MEMS capacitive humidity sensing element and a band-gap temperature sensor, while the BMP280 employs a piezoresistive pressure sensing element.
Designed for seamless integration, the board supports a wide 2.0V to 5V logic level, accommodating both 3.3V and 5V microcontroller systems without level shifting. The inclusion of both a 4-pin Grove connector and a row of solderable pins offers flexibility for rapid prototyping or permanent PCB installation. This module is engineered for applications requiring reliable, multi-parameter environmental data with minimal footprint and power draw.
