Motion Sensor Circuit Diagrams Please Help Design A Simple Circuit On Pir Sensor?

Please help design a simple circuit on pir sensor? - motion sensor circuit diagrams

The aim is to provide a system for the PIR sensor design, the body temperature of man being.and I am not entitled to the software for this circuit.The the output signal of the sensor should detect using pulse-width modulator input and the entering a motor exit circuit.basically forward / backward when the sensor human body heat engine that is determined to drive more slowly when the motor does not normally get answers ABIT faster.i PIR sensor detects movement, do not want that to PIR diagram.I motion.Please in designing a simple circuit must seriously this.Thanks in the detection
