Human Body Sensor Designing Circuit Please Help Design A Simple Circuit On Pir Sensor?

Please help design a simple circuit on pir sensor? - human body sensor designing circuit

The aim is to develop a plan for the PIR sensor to detect the body temperature of a person not authorized being.and Clock, software for these circuit.The sensor output to the input of the PWM pulse utilization and output, it will enter the engine circuit.basically forward / backward when the sensor human body heat engine that will drive more slowly when the motor is not yet determined faster.i ABIT general replies PIR sensor detects movement, do not want the PIR must diagram.I to motion.Please in designing a simple circuit seriously this.Thanks in the detection
