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
