Abstract: An apparatus of the subject technology includes a housing, a first sensor to obtain a first measurement, an optional second sensor to obtain a second measurement, and a processor to determine a seal-quality metric of the housing based on the first measurement and the second measurement. The first sensor can include an internal pressure sensor disposed inside the housing, and the first measurement can include measurement of an internal pressure of the housing. The second sensor can include an external pressure sensor disposed at an outside wall of the housing, and the second measurement can include measurement of an external pressure.
