Einführung
WF280A is a high precision barometer and altimeter especially designed for consumer applications. It measures the pressure
based on piezo-resistive MEMS pressure sensor.
Der Ultra-Low-Power, low voltage electronics of the WF280Ais optimized for use in mobile phones, Smartwatches, PDAs, GPS-Navigationsgeräte und Outdoor-Ausrüstung. 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 -Pakethöhe. Seine kleinen Abmessungen und der geringe Stromverbrauch ermöglichen die Implementierung in batteriebetriebenen Geräten. With a low altitude noise of merely 0.1m and very low offset temperature coefficient (Gesamtbetriebskosten), 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.
