Hardware include the whole programming of circuit, design, anti-jamming circuit, principal chart of circuit, the circuit board of PCB, jointing the circuit, debugging and assemble the system.

This system adopted the single computer AT89S52, the hardware circuit was very simple and it had the characteristics of high anti-jamming capabilities and a strong ability to identify.

This temperature control system used improved PID control arithmetic in software, fully considered measure of anti-jamming in hardware, the chart circuit and software flow chart are offered.
