The electronic device is provided with an automatic leak detection means, notably for a gas leak, in the case of the device. The automatic leak detection means includes a pressure sensor, a temperature sensor and a calculation unit connected to the pressure sensor and to the temperature sensor. The calculation unit, which is a microcontroller, the pressure sensor and the temperature sensor are arranged inside the case. In operation, the microcontroller checks, based on measurements performed by the pressure sensor and the temperature sensor over time, whether the variation in pressure in the case is within a defined margin proportional to the variation in temperature 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 a pressure sensor, a temperature sensor and a calculation unit connected to the pressure sensor and to the temperature sensor, the calculation unit, the pressure sensor and the temperature sensor being arranged inside the case, and wherein the calculation unit is intended to check, based on measurements made by the pressure sensor and the temperature sensor over time, whether or not the variation in pressure inside the case is proportional to the variation in temperature to determine whether or not the case has a sufficient degree of sealing.
