WF5805F is a high precision barometer and altimeter especially designed for consumer applications. It measures the pressure based on piezo – resistive MEMS pressure sensor The ultra – low power, low voltage electronics of the WF5805F is optimized for use in mobile phones, smart watches, PDAs, GPS navigation devices and outdoor equipment. The sensor module is housed in a compact 8 – pin metal – lid LGA package with a footprint of only 4.5×4.5 mm² and 3.5 mm package height. Its small dimensions and its low power consumption allow the implementation in battery driven devices. With a low altitude noise of merely 0.08m and very low offset temperature coefficient(TCO), the WF5805F offers superior performance and cost are perfectly suitable for applications like flying toys and sport watches. The I²C / SPI interface allows for easy system integration with a microcontroller.
