Unit Mini BPS

SKU:U090

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
