BMP085 (Barometric Pressure Sensor Module for Arduino)

The 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.

Features:

- Pressure range: 300 ~ 1100hPa (altitude 9000 m ~ -500 m); - Working voltage: 1.71 - 3.6VDC; - Low power consumption: 4μA; - High precision: at low-power mode, the resolution is 0.06hPa (0.5 meters); - Temperature output; - Communication interface: I2C or SPI; typical application: - GPS precise navigation (dead reckoning, the upper and lower bridge detection, etc.); - indoor and outdoor navigation; - The weather forecast; - The vertical velocity indication (rise / sink speed); Note: You need to add 5V to 3.3V level converter circuit between Arduino UNO R3 and the module.

Now mounted on a breakout board, the MPL115A1 is a digital barometer that uses MEMs technology to give accurate pressure measurements between 50kPa and 115kPa. We stock the SPI interface version of the sensor. Average current consumption is 10µA at one measurement per second.The sensor outputs both temperature and pressure readings on the SPI bus. See page 3 of the datasheet for information on how to take readings from the pressure sensor.
