Barometer Tag

In Stock

Barometer Tag allows to measure absolute pressure in the range from 20 kPa to 110 kPa, or altitude above the sea level in meters. It uses a low-power sensor MPL3115A2 with absolute accuracy of ±0.4 kPa.

Monitoring of absolute pressure is useful for weather forecast and it is also important parameter in biometeorology because the absolute pressure can affect our health.

This sensor is a digital I2C-only peripheral featuring a very low active and standby current.
