M5 Stack Barometric Pressure Unit

Barometric Pressure Unit is a barometer unit, which uses a Bosch bmp280 pressure sensor to measure atmospheric pressure and estimate 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.

Applications:

1. Wearable devices
2. Motion tracking
3. UAV attitude determination

Features:

1. Air pressure sensor, with a temperature sensor on-chip, can be measure simultaneously
2. The accuracy is ± 0.12hpa
3. Temperature drift coefficiency 1.5pa/k
4. Supports periodic measurement
5. Internal integrated 5-segment filter
6. Support low power consumption
7. Development platform: Arduino, uiflow (Blockly, Python)
8. 2x LEGO compatible holes

Package Includes:

1x Barometric Pressure Unit

1x Grove Cable(5cm)
