Abstract: The purpose of this project is to design a system for US Border Patrol that can be used to detect illegal immigrants or terrorists that are trying enter United States illegally. Introduction: The US Border Patrol has asked us to develop a low-cost sensor system that detects potential illegal immigrants or terrorists that may be trying to smuggle themselves into the US by hiding in container trucks crossing the border. Using piezoelectric force sensors, we will try to find high pass characteristics of a load cell to effectively remove the “dead weight” of the truck and its cargo leaving the forces of human activities to be amplified using the high gains of a charge amplifier. Any truck that contains these small movement forces, should be considered suspect and dealt with accordingly. Proposed Design: Our design consists of a PCB Piezotronics Model 218C load cell connected to a Kistler Model 5004 charge amplifier, which is then connected to an oscilloscope and a computer as shown in Fig. 1. First, the truck driver must pull his truck onto the platform that contains the PCB Piezotronics load cell. The driver must turn off and exit the truck and platform, so his or her movements or the movements of a running vehicle will not be recorded by the system. The
