BMP280 Sensor Module (Pack of 25)

BMP280 Sensor Module

The BMP280 sensor module is an absolute barometric pressure sensor specially designed for mobile applications. Its small dimensions and low power consumption allow for the implementation of compact battery-run devices like mobile phones and watches.

This BMP280 is a tiny Atmospheric Sensor Breakout to measure barometric pressure, and temperature readings all without taking up too much space. Basically, anything you need to know about atmospheric conditions you can find out from this tiny breakout. The BMP280 Breakout has been design 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 a temperature, and 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 1.0C 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.

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
• Health care applications (e.g. spirometry)
