Description

Thanks to Bosch for this environmental sensor at low cost, the barometric sensor based on the final sensor BMP280, which ets an evolution of the BMP180 sensor. This sensor allows a barometric measure of accuracy as well as a measure of temperature. The pressure can be measure of 300 hPa to 1100 hPa with a precision of ±1 hPa. the extended temperature is-40 ° C to + 85 ° C with a precision of ±1 °.

As the pressure varies with the altitud, you can measure with an accuracy of 1 m altitude. This module works as well in I2C and SPI.

Sold with a cable Grove.
