DESCRIPTION :
BMP280 Barometric Pressure and Altitude Sensor Module 3.3V is manufactured by Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. 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.
Features:
- Get more precise temperature, atmospheric pressure values, and approximate altitude data
- 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)
- Vertical velocity indication (e.g. rise/sink speed)
- Libraries and tutorials available for Arduino and other micro-controllers
- Operating Voltage: 1.71V to 3.6V – would typically be operated from 3.3V
- Accuracy between 700 to 900hPa and 25 to 40 deg. C: ±0.12hPa and ±1.0m
