Barometric pressure sensor for high-accuracy fall detection

Barometric pressure sensor detects the atmospheric pressure. This sensor is used for indoor navigation, elevator/floor change detection and weather monitoring. Murata's sensor element is designed by capacitive sensing technology, which performs low current consumption, low noise and good stability for temperature change.

Murata's barometric pressure sensor (ZPA4756-0311A-R) is compact, highly accurate and consume low power. Its compact package offers a high degree of freedom in design and its low power consumption enables long operating times. Therefore, it is being used in a wide range of applications including wearable devices, the wellness market and industrial equipment. The product with waterproof functionality is suitable for devices that require higher levels of waterproof performance, like underwater applications, in addition to environments such as those with sweat and rain. Accordingly, this product will contribute to the wearable field.
