Feature

●The BME 280 sensor is a precision sensor soldered to the circuit board, not only the pressure and temperature, this sensor can also measure the humidity.
●It uses both the I2C and SPI interface (supports 3, 4-wire SPI). Interface: I2C (up to 3.4MHz); SPI (up to 10MHz)
●The temperature humidity module is ideal for all types of weather sensors and can even be used in both I2C and SPI. For simple and easy wiring, choose I2C. If you want to connect a range of sensors without worrying about I2C address collisions, choose SPI
●The BME 280 atmospheric pressure sensor consists of a very accurate pressure sensor and an associated temperature sensor that helps calibrate the pressure readings
●The BME 280 sensor is a precision sensor solution for measuring air pressure with an absolute accuracy of ±1 hPa and temperature with an accuracy of ±1.0 °C. As the pressure changes with height and the pressure measurements are good, you can also use it as an altimeter with an accuracy of ± 1 meter
