M5stack Grove - Barometer Sensor（BMP280)
€6.00
Tax included
The Barometric Pressure Unit integrates the Bosch BMP280 pressure sensor to measure atmospheric pressure and estimate altitude. With a relative accuracy of ± 0.12 hPa, it corresponds to an altitude difference of ± 1 m. The temperature drift coefficient is very low at 1.5 Pa/K (12.6 cm/K). Additionally, an integrated temperature sensor is present on the chip.
