A handy surveillance system for e-life applications

This paper presents a handy surveillance system design and implementation for e-life applications. This system includes GPRS data communication, microprocessor control, I/O data processing, and energy management. A TCP/IP embedded GPRS module is adopted to simplify the circuit by activating using an 8051 microprocessor with memory. Through design process, this finish system is miniaturized into battery-supply for long lasting operation. Tests have been carried out to verify some important functions with reliability and stability
