소개
WF280A is a high precision barometer and altimeter especially designed for consumer applications. It measures the pressure
based on piezo-resistive MEMS pressure sensor.
초저전력, low voltage electronics of the WF280Ais optimized for use in mobile phones, 스마트 시계, PDA, GPS 내비게이션 장치 및 실외 장비. The sensor module is
housed in a compact 8-pin metal-lid LGA package with a footprint of only 2.0 × 2.5 mm2 and 1.0 MM 패키지 높이. 작은 치수와 저전력 소비는 배터리 구동 장치의 구현을 허용합니다.. With a low altitude noise of merely 0.1m and very low offset temperature coefficient (TCO), the WF280A offers superior performance and are perfectly suitable for applications like floor detection, health care as well as GPS refinement. The I2C interface allows for easy system integration with a microcontroller.
