Description

Barometric Pressure Unit is a barometer unit, which integrates the Bosch BMP280 pressure sensor to measure atmospheric pressure and estimate the altitude. The relative accuracy can reach ± 0.12hpa, equivalent to ± 1m height difference. At the same time, the temperature drift coefficient is very low, which can reach 1.5 PA / K, that is, the temperature drift is 12.6 cm / K. in addition, there is an integrated temperature sensor in the chip.

    Cute little device.

    It's small and perfectly designed. The sensor is nice and accurate, and changes between the ground and the ceiling... always a good sign! It's easy to code for, and comes (like always) with example code for you to get started. Using the grove plug and cable makes it simple to plug in. I love it!
