Detection Logic

Detection Logic is the core processing component of Tamper Detection Circuitry that implements the decision-making algorithms. It receives signals from various sensors (such as motion, vibration, magnetic field, or continuity sensors) and applies predefined rules, thresholds, or machine learning models to distinguish between normal environmental conditions and actual tampering attempts. Its output typically triggers security responses like alarms, data erasure, or system shutdown. The detection logic continuously monitors input signals from connected sensors. It compares these signals against baseline profiles and configured thresholds. When sensor readings deviate beyond acceptable limits (e.g., unexpected enclosure opening, abnormal vibration patterns, or magnetic field disruption), the logic evaluates these anomalies using programmed algorithms. This may involve pattern recognition, statistical analysis, or state machine transitions to confirm tampering before activating protective measures. The component is fabricated on semiconductor silicon and operates within specified electrical and environmental parameters. For instance, the supply voltage range is 3.3–5 V DC, and the operating temperature range is -40 to 85 °C. The detection threshold is set between 10 and 100 mV, and the response time is 1 to 10 ms. The input impedance is at least 1 MΩ, and the output logic levels are 0–0.4 V for low and 2.4–5 V for high, compliant with IEC 61131-2. The power dissipation is limited to 50 mW, and the ESD tolerance is ±2 to 8 kV per IEC 61000-4-2. The humidity range is 5–95% RH (non-condensing), and the ingress protection rating is IP40 to IP67. The weight ranges from 5 to 20 g. These values are reference ranges and must be verified for the specific model and application. Standards such as IEC 62368-1, IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-78, and IEC 60529 are listed as procurement references, not as proof of certification. Always confirm model-specific specifications and compliance with the legal manufacturer or supplier.
