Key Features Trip-wire detection: alarms upon cutting or breaking the circuit. Compact form factor—ideal for small security setups. Can include siren output or notification functionality. Technical Specs (based on typical DIY electronic principles) Power: 5?V via battery or USB. Sensor: wire loop forms part of circuit. Detects open (cut) or short. Output: buzzer or siren (?80?dB). Additional: LED status indicator, normally-closed circuit style. Enclosure: plastic or 3D-printed housing. Optional modules: GSM or Wi?Fi module (e.g. ESP8266) for notifications. DIY Considerations Frame wire in series with supply; alarm triggers on circuit break. Use comparator circuit or microcontroller to sense wire integrity. Add buzzer or wireless module for alerting.
