This paper presents the development of a compact leak detector for vacuum systems that operates using hydrogen as a tracer gas, detected by a semiconductor MQ-8 sensor. The sensor is connected to an Arduino microcontroller, enabling digital signal processing and real-time visualization through the Processing software environment. The designed device is capable of detecting even small hydrogen leaks caused by imperfect sealing of vacuum connections. It is characterized by simplicity, low manufacturing cost, and suitability for laboratory use as an alternative to helium leak detectors. Experimental tests confirmed the effectiveness and stability of the developed leak detector during long-term measurements.
