WF27HH 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 WF27HH is optimized for use in mobile phones, smart watches,PDAs, GPS navigation devices and outdoor equipment. The sensor module is housed in a compact 10-pin metal-lid
LGA package with a footprint of only 2.7 × 2.7 mmP P and 1.81 mm package height. Its Digital Baromete 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 WF27HH offers superior performance and cost are perfectly suitable for applications like flying toys and sport watches. The IIC/SPI interface allows for easy system integration with a microcontroller.
