This project aims to develop a system using Arduino Uno microcontroller to monitor the vital signs and location of prisoners. The system includes a heart rate sensor and a DS18B20 body temperature sensor to continuously monitor the heart rate and body temperature of the prisoner. The acquired data is then stored and updated in a PLX-DAQ database. In addition to monitoring the vital signs, the system utilizes Receive Signal Strength Identification (RSSI) technology to track the signal strength of the prisoner. If the prisoner attempts to escape, the signal strength will decrease due to the increased distance from the monitoring system. This change in signal strength serves as an indicator of a potential escape attempt. By continuously monitoring the vital signs and signal strength, the system provides real-time data to identify any abnormal or suspicious activities. In the event of a significant drop in signal strength indicating an escape attempt, appropriate actions can be taken to prevent the prisoner from escaping. This project enhances prison security and enables prompt response to escape attempts by leveraging technology and monitoring systems. It ensures the safety of prisoners and assists in maintaining a secure prison environment. The collected data can also be used for further analysis and evaluation of prisoner health and behaviour patterns, contributing to improved prison management and security protocols.
