Abstract: A system for real-time detection and prevention of physical and digital tampering in electronic weighing and measuring instruments. It functions as an attachable retrofit module or a standalone device. Security includes physical sensors (rotary encoders, Reed switches), an INA219 current sensor for analog voltage detection, 3- point calibration for linearity assessment, and cryptographic hash-chain firmware verification. Upon tampering, the device enters "Safe Mode," halting measurements, and requires an authorized, cloud-generated clearance token for restoration.
