The electronic device (1) is provided with an automatic leak detection means, notably for a gas leak, in the case (2) of the device. The automatic leak detection means includes an internal pressure sensor (3), an external pressure sensor (4) and a calculation unit (5) connected to the internal pressure sensor and to the external pressure sensor. The calculation unit, which is a microcontroller, and the internal pressure sensor are arranged inside the case, whereas the external pressure sensor is arranged on an external surface of the case. The microcontroller (5) checks, based on measurements performed by the pressure sensors over time, whether the pressure variation inside the case is different from the pressure variation outside the case to determine whether or not the case has a sufficient degree of sealing.
An electronic device, which is provided with an automatic leak detection means of a case of the electronic device, wherein the automatic leak detection means includes an internal pressure sensor, an external pressure sensor and a calculation unit connected to the internal pressure sensor and to the external pressure sensor, the calculation unit and the internal pressure sensor being arranged inside the case, whereas the external pressure sensor is arranged on an external surface of the case, and wherein the calculation unit is configured to check, based on respective measurements made by the internal pressure sensor and the external pressure sensor over time, whether or not the variation in pressure inside the case is different from the variation in pressure outside the case to determine whether or not the case has a degree of sealing above or below a determined limit.
