導入
WF280A is a high precision barometer and altimeter especially designed for consumer applications. It measures the pressure
based on piezo-resistive MEMS pressure sensor.
超低力, low voltage electronics of the WF280Ais optimized for use in mobile phones, スマートウォッチ, PDAS, GPSナビゲーションデバイスと屋外機器. 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パッケージの高さ. その小さな寸法とその低消費電力により、バッテリー駆動型デバイスでの実装が可能になります. 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.
