GY-BMP280 Barometric Atmospheric Pressure Sensor

Description

“Introduction
The BMP280 Breakout Board is the easy way to measure pressure and humidity, and without taking up a lot of room. It gives you easy to solder 0.1″” headers, runs I2C or SPI, takes measurements at less than 1mA and idles less than 5uA (yes, microamps!).

The BMP280 can be used to take pressure, humidity, and temperature readings. Use the data to get relative altitude changes, or absolute altitude if the locally reported barometric pressure is known.

Ranges:

Temp: -40C to 85C
Humidity: 0 – 100% RH, =-3% from 20-80%
Pressure: 30,000Pa to 110,000Pa, relative accuracy of 12Pa, absolute accuracy of 100Pa
Altitude: 0 to 30,000 ft (9.2 km), relative accuracy of 3.3 ft (1 m) at sea level, 6.6 (2 m) at 30,000 ft.
