Pressure Sensor Module BMP280 for Arduino Projects
Pressure Sensor Module BMP280 for Arduino Projects High Precision Atmospheric Sensor
BMP280 sensor is 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 1.00C 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.
Typical application:
Enhancement of GPS navigatione.g.time-to-first-fix improvementdead-reckoningslope detection Indoor navigationfloor detectionelevator detectionOutdoor navigationleisure and sports applications, weather forecast, health care applicatione.g. sirometry); Vertical velocity indicatione.g. risk/sink speed); Target devices, handsets such as mobile phones,table PCs, GPS devices, navigation systems, portable health caredevices, home weather stations, flying toys, watches
Connect the following BMP280 pins to the Arduino respectively, VCC to 3.3V, GND to GND, SCL to A5, and SDA to A4.
