Barometric Pressure Unit

SKU:U090

Description

Barometric Pressure Unit is a barometer unit, which integrates the Bosch BMP280 pressure sensor to measure atmospheric pressure and estimate the 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.

Product Features

  • Air pressure sensor, with temperature sensor on chip, can be measure simultaneously
  • The accuracy is ± 0.12hpa
  • Temperature drift coefficiency 1.5pa/k
  • Supports periodic measurement
  • Integrated 5-segment filter
  • Support low power consumption
  • Development platform: Arduino, UIFlow (Blockly, Python)
  • 2x LEGO™ compatible holes

Include

  • 1x Barometric Pressure Unit
  • 1x Grove Cable (5cm)

Application

  • height detector
  • Weather station
