Waveshare BME280 Environmental Sensor, Temperature, Humidity, Barometric Pressure

Overview

A tiny sensor breakout with BME280 onboard, sensing environmental temperature, humidity, and barometric pressure. It supports both I2C and SPI interfaces, also is compatible with 3.3V/5V voltage levels.

Due to its ultra small form factor, low power consumption, high precision with stability, the BME280 Environmental Sensor is suited for applications such as environment monitoring, weather forecast, altimeter, and IoT projects, and so on.
