BME280 Environmental Sensor
Sensor enable real-time monitoring of temperature, humidity and barometric pressure

This product is a high-precision environmental sensor equipped with a BME280 sensor. It allows for monitoring of temperature, humidity, and barometric pressure. The chip can sense temperatures ranging from -40 to +85°C, humidity from 0 to 100%, and barometric pressure from 300 to 1100hPa. The module can be connected to a development board for environmental detection using a PH2.0 6PIN wire. Demo codes are available for Arduino, Raspberry Pi (in both C and Python), and STM32 versions. These demo codes enable real-time monitoring of temperature, humidity, and barometric pressure.
