BME280 Environmental Sensor
A tiny sensor breakout with BME280 onboard, sensing environmental temperature, humidity and barometric pressure. It supports both I2C and SPI interfaces and is compatible with 3.3V/5V voltage levels.
Due to its ultra-small form factor, low power consumption, high precision and stability, the BME280 is well-suited for applications such as environment monitoring, weather forecast, altimeter and IoT projects.
The sensor comes with a 20cm PH2.0 6-pin wire.
