Devices such as smartphones and smartwatches, which are used in various environments, require a robust, waterproof design. Although a waterproof design can be achieved by hermetically sealing the housing, doing so cuts off the sensor inside from the outside environment, making it impossible to gain accurate atmospheric pressure value readings.
Waterproof film can also be used to keep water entering into the interior, however, the structure makes it difficult to achieve a high-pressure waterproof design.
Murata waterproof barometric pressure sensors maintain a high level of waterproof performance and is mounted on the housing.
They can also directly sense outside spaces for responsive, accurate measurements.
