This paper presents a comprehensive experimental framework for determining the angular-rate threshold of a bistable gyroscope. To overcome the noise and drift inherent in conventional continuous measurements, the proposed LabVIEW-based system integrates a centrifugal excitation unit controlled via Modbus RTU with a high-speed infrared sensor network. This distributed architecture detects snap-through transitions and timestamps them with millisecond resolution, enabling accurate, event-driven threshold extraction without analog signal integration. System durability and repeatability were rigorously evaluated through 100 activation cycles across 20 independent measurement sessions. Experimental results demonstrate distinct, highly consistent state transitions, with the measured threshold concentrated around 246–250 rpm. This aligns well with the 260 rpm analytical prediction, and the ~5% deviation is mainly attributed to polymer thermomechanical hysteresis and micro-machining tolerances. Ultimately, this framework offers a robust, drift-resistant measurement solution for accurately characterizing event-driven inertial sensors.
