Introduction
BMP280 is an absolute barometric pressure sensor specifically designed for mobile applications and the sensor module is housed in a very compact package. Its diminutive dimensions and low power consumption allow for the implementation of battery-powered devices. A barometric sensor is ideal for measuring diverse weather conditions and has excessive accuracy and low cost making it an excellent solution for precision strain measurements of as much as ± 1 hPa and a temperature of as much as ±1.0°C. Because the stress changes with altitudeand pressure measurements are very accurate, you may use this sensor and the altimeter ± 1-meter accuracy.
Features of BMP280 Barometric Pressure Sensor
- Weather forecast Health care application（e.g. sirometry）
- Using Immersion Gold PCB, machine welding process to ensure quality
- Compatible with any controller, processor, and Arduino
- Supports both I2C and SPI communication or interface
