Introduktion
WF280A is a high precision barometer and altimeter especially designed for consumer applications. It measures the pressure
based on piezo-resistive MEMS pressure sensor.
Den ultralåga kraften, low voltage electronics of the WF280Ais optimized for use in mobile phones, smarta klockor, Pdas, GPS -navigationsapparater och utomhusutrustning. 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 pakethöjd. Dess små dimensioner och dess låga effektförbrukning möjliggör implementeringen i batteridrivna enheter. 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.
