AHT20+BMP280 Temp Humidity Pressure Sensor Module

The AHT20+BMP280 Temperature, Humidity, and Barometric Pressure Module is an all-in-one environmental sensor breakout board designed for high-precision atmospheric monitoring. By combining the AHT20 humidity/temperature sensor and the BMP280 barometric pressure sensor on a single ultra-compact PCB, this module provides comprehensive environmental telemetry over a simple I2C interface. It is the perfect solution for space-constrained DIY electronics, weather stations, and IoT projects requiring highly accurate climate data.

This dual-sensor module is fully compatible with popular microcontrollers like Arduino, ESP32, ESP8266, and Raspberry Pi. The AHT20 offers superior stability and accuracy for relative humidity and temperature, while the BMP280 delivers precise barometric pressure readings that can also be used to calculate altitude (altimeter function). Operating on a standard I2C bus, it simplifies wiring and reduces the required GPIO pins, making it incredibly easy to integrate into smart agriculture, home automation, and drone telemetry systems.

Features:

• Dual-Sensor Integration: Combines AHT20 (humidity & temp) and BMP280 (pressure & temp) on a single compact board.
• High Precision: Offers ±2% RH humidity accuracy and ±0.3°C temperature accuracy.
• Barometric Altimeter: Measures atmospheric pressure from 300 hPa to 1100 hPa, enabling precise altitude calculations.
• I2C Interface: Uses a shared I2C bus (SDA/SCL) for easy communication with microcontrollers.
• Wide Voltage Compatibility: Operates reliably within a 3.3V to 5V DC range.
• Ultra-Compact Design: Lightweight (only 2g) and small footprint, ideal for portable and wearable devices.
