This product is EOL. Please order the new version Unit Mini BPS v1.1
Description
Unit Mini BPS is a barometer unit that uses the Bosch BMP280 pressure sensor for measuring atmospheric pressure and altitude estimation. The relative accuracy can reach ±0.12 hPa, equivalent to a height difference of ±1 m. Additionally, it has a very low temperature drift coefficient of 1.5 Pa/K, meaning a temperature drift of 12.6 cm/K. Furthermore, a temperature sensor is integrated within the chip.
