Waveshare BME280 Environmental Sensor
3.690 Ft
Taxes included.
Tiny combo sensor board based on Bosch BME280. Reads temperature, relative humidity, and barometric pressure in one go. Works over I²C or SPI and plays nice with 3.3 V and 5 V hosts (onboard regulator/level shifting).
Highlights
-
3-in-1: Temp + RH + Pressure
-
I²C (0x76/0x77) or SPI selectable
-
3.3–5 V friendly breakout (plug ’n’ play with Pico, ESP32, Arduino)
-
Low power, fast readings; great for weather stations & indoor climate
