BME280 Altimeter Barometric Pressure Temperature Humidity Sensor Module 3.3V

The BME280 is a combined digital humidity, pressure and temperature sensor based on proven sensing principles. Its small dimensions and its low power consumption allow the implementation in battery-driven devices such as handsets, GPS modules or watches. Anything you need to know about atmospheric conditions, you can find out from this tiny breakout. The BME280 Breakout has been designed to be used in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring.

The onboard BME280 sensor measures atmospheric pressure from 30kPa to 110kPa, as well as relative humidity and temperature. This module uses an environmental sensor manufactured by Bosch with temperature, a barometric pressure sensor that is the next generation upgrade to the popular BMP085/BMP180/BMP183 Sensor.

This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI! This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy. The BME280 is the next generation of sensors from Bosch and is the upgrade to the BMP085/BMP180/BMP183 – with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications but can use either I2C or SPI. For simple, easy wiring, go with I2C. If you want to connect a bunch of sensors without worrying about I2C address collisions, go with SPI.
