Description

BMP280 Digital Barometric Pressure & Altitude Sensor especially designed for mobile applications. The sensor module is housed in an extremely compact package. Its small dimensions and its low power consumption allow for the implementation in battery driven devices such as mobile phones, GPS modules or watches.

As its predecessor BMP180, the BMP280 is based on Bosch’s proven piezo-resistive pressure sensor technology featuring high accuracy and linearity as well as long term stability and high EMC robustness

Basically, anything you need to know about atmospheric conditions you can find out from this tiny breakout. The BMP280 Breakout has been designed to be used in indoor/outdoor navigation, weather forecasting, home automation, and even personal health and wellness monitoring.

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 BMP280 is the next-generation of sensors 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.

BMP280 APPLICATIONS

  • Enhancement of GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection)
  • Indoor navigation (floor detection, elevator detection)
  • Outdoor navigation, leisure and sports applications
  • Weather forecast
  • Vertical velocity indication (e.g. rise/sink speed)
  • Get more precise temperature, atmospheric pressure values, and approximate altitude data
  • Health care applications (e.g. spirometry)
