GY-BMP280-3.3 High Precision Atmospheric Pressure Sensor

This module uses the BMP280 which is a digital Atmospheric pressure sensor. Typical uses include:

• 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).

It uses I2C interface as well as SPI interface.

Technical Specifications:

• Sensing range: 30kPa - 110kPa (3 - 11Bar)
• Voltage range: 1.71V - 3.6V
• Working current: 1.1mA
• Sleep Current: 0.003mA
