Expert Verdict
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.
Best For
For makers needing compact, accurate environmental sensing with easy Grove/I2C connectivity. Avoid if you require SPI interface or separate sensors.
