AHT20 BMP280 2-in-1 Temp Humidity Pressure Sensor I2C Module 3.3V-5V for Arduino ESP32 Raspberry Pi DIY Weather Station
Computer Peripherals
“The AHT20+BMP280 module delivers high-accuracy temperature (±0.3°C), humidity (±2% RH), and pressure (±1 hPa) sensing via I2C in a compact board. Its low power draw and Grove connector simplify rapid prototyping for weather stations and IoT devices — a solid choice for makers, though it lacks SPI or individual sensor outputs.”
