p{margin-block-start: 0; margin-block-end: 0}All-in-One Environmental Sensing: Precision Data for Temperature, Humidity, and Pressure.
Key Features & Benefits
3-in-1 Precision: Combines AHT20 and BMP280 for simultaneous, high-accuracy reading of temperature, humidity, and barometric pressure.
Digital & Stable: I2C digital output ensures stable data transmission, resistant to interference.
Easy to Power: Wide operating voltage (3.3V to 5V DC), compatible with Arduino and ESP32 without complex power regulation.
Plug & Play: Standard GROVE 4-pin connector allows for quick connection without soldering.
Low Power Consumption: Optimized for battery-powered applications and long-term monitoring.
Product Description
Need reliable environmental data for your project? This compact module packs two premium sensors (AHT20 & BMP280) into one board, delivering three key metrics at once. Simplify your weather station, smart home climate control, or IoT device with easy I2C integration.
Important Notes / How to Use
I2C Address Conflict: This module contains two I2C devices. The AHT20 address is 0x38, and the BMP280 address is 0x76 or 0x77. Ensure your code uses the correct addresses for each sensor.
Voltage Level Compatibility: The I2C logic level must match your microcontroller. If using a 5V MCU (like Arduino Uno), verify I2C line 5V-tolerance or use a level shifter.
Software Library Required: You MUST install the dedicated Arduino libraries for AHT20 and BMP280 (e.g., Adafruit_AHTX and Adafruit_BMP280) for proper operation.
Environmental Factors: For accurate readings, avoid placing the module near heat sources or in direct sunlight.
