HOPERF HP203N Digital MEMS Absolute Barometric Pressure Sensor

Specifications

Product Introduction

The HP203N is a high-precision barometer and altimeter sensor that measures pressure and temperature using an internal 24-bit ADC and compensates them with an integrated algorithm. The fully-compensated values can be read out via the I²C interface by an external MCU. The uncompensated values can also be read out in case the user wants to perform their own data compensation. The device can also compute the value of altitude according to the measured pressure and temperature.

  • Supply voltage: 1.8V to 3.6V
  • Pressure range: 300mbar~1200mbar
  • Fully compensated data
  • Direct Reading, compensated:
    • Pressure: 20-bit measurement (Pascals)
    • Altitude: 20-bit measurement (Meters)
    • Temperature: 20-bit measurement (Degrees Celsius)

Applications

  • Mobile altimeter / barometer
  • Industrial pressure and temperature sensor system
  • Adventure and sports watches
  • Weather station equipment
  • Data loggers for pressure, temperature and altitude
