WF280A is a high precision barometer and altimeter especially designed for consumer applications. It measures the pressure
based on piezo-resistive MEMS pressure sensor.
Ultra düşük güç, low voltage electronics of the WF280Ais optimized for use in mobile phones, Akıllı Saatler, PDA'lar, GPS navigasyon cihazları ve dış mekan ekipmanı. 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 Paket Yüksekliği. Küçük boyutları ve düşük güç tüketimi, pil odaklı cihazlarda uygulamaya izin verir. 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.
