Abstract
A water detecting pressure-sensing device includes a metal housing including a cavity. A pressure sensor is disposed on a die and configured to generate a signal in response to a pressure variation. A protection medium at least partially fills the cavity and covers the die. One or more electrodes are disposed on the die and are used to detect a presence of a water droplet on the protection medium.
