Description
Thanks to Bosch, now we’ve got a high-precision environmental sensor at even lower cost, the
Grove – Barometer Sensor(BMP280). It is based on their new BMP280 sensor, which is an
upgraded version of the old BMP180 used in Grove – Barometer Sensor (BMP180). The module
provides precise measurement of barometric pressure and temperature in the environment.
The air pressure can be measured in a range from 300 hPa to 1100hPa with ±1.0 hPa absolute
accuracy. As for the temperature the sensor works perfectly for temperatures between - 40 and
85 with an accuracy of ±1.
Owing to its high accuracy on measuring the pressure, and the pressure changes with altitude,
we can calculate the altitude with ±1 meter accuracy, which makes it a precise altimeter as well.
Another great thing about this module is that, you don’t even need to worry about the I2C
collisions as it provides both I2C and SPI interfaces. To use SPI, simply de-solder the bonding
pads on the back. If you go with I2C, the board also provides 2 I2C addresses for you to select as
you want.
Note: As the sensor is quite sensitive to the environmental conditions, please DO NOT touch it
with your fingers.
