[EOL] Barometric Pressure Unit(BMP280)
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.
Features
- Pressure sensor with on-chip temperature sensor, capable of measuring temperature simultaneously
- Accuracy up to ±0.12hPa
- Temperature drift coefficient 1.5Pa/K
- Supports periodic measurement
- Integrated 5-stage filter
- Supports low power consumption
- I2C communication: 0x76
- Development platforms: Arduino, UIFlow (Blockly, Python)
- 2 x LEGO compatible holes
Includes
- 1 x Unit Mini BPS
- 1 x HY2.0-4P Grove connection cable (5cm)
Applications
- Altitude detection
- Weather stations
