Waveshare BME280 Environmental Sensor
Waveshare BME280 Environmental Sensor
The Waveshare BME280 Environmental Sensor is a compact breakout board designed for precise measurement of temperature, humidity, and barometric pressure. Supporting both I2C and SPI interfaces, and compatible with 3.3V/5V voltage levels, the BME280 Dev Board is ideal for Linux-based IoT projects, weather monitoring, and embedded applications.
Thanks to its ultra-small form factor, low power consumption, and high precision with stability, the Waveshare BME280 Environmental Sensor is well-suited for environment monitoring, weather forecasting, altimeter functions, and IoT development.
