M5Stack Barometric Pressure Unit (BMP280)

• M5Stack Barometric Pressure Unit (BMP280)
• Uses Bosch bmp280 pressure sensor
• Provides temperature drift coefficiency 1.5pa/k
• Features internal integrated 5-segment filter
• Low power consumption
• Supports periodic measurement
• Development platform: Arduino, uniflow (Blockly, Python)

The M5Stack Barometric Pressure Unit (BMP280) 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.

Application

• Wearable devices
• Motion tracking
• UAV attitude determination
