BMP280 I2C / SPI Digital 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.
