Body Temperature Sensor Circuit Diagram Please Help Design A Simple Circuit On Pir Sensor?

Please help design a simple circuit on pir sensor? - body temperature sensor circuit diagram

The aim is to provide a system for the PIR sensor design, the body temperature of man being.and I am not permitted to recognize software for this circuit.The sensor output to the input of the PWM pulse utilization and output is it gives you 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
