Intelligent Energy Saving System can be used in places like where lighting is very important. The libraries will be well illuminated with many lamps. When people are not present at a reading place the lighting can be made OFF and when they are present, the lighting made ON. All these can be done through by Dimming circuit and PIR sensor.
If a person entering to the monitored area, the PIR sensors activates and sense the person, gives to the micro controller. The Infrared energy emitted from the living body is focused by a Fresnel lens segment. Then only the PIR sensor activates. After sensing the person LDR checks the light intensity of the monitored area, whether it is bright or dark. Depending on the LDR output, the lamp may be ON / OFF by using Dimmer circuit.
By using this system we can adjust the speed of Fan according to the room temperature measured by Thermostat, which is connected to the micro controller. To display the room temperature of PIR mode operation we are using the LCD display.

  1. 1. Human Presence Detection Based Room Light Controller Using PIR SENSOR Guided by SUBMITTED BY RAVI PRAKASH VERMA Nikhil Singhia (ASSISTANT PROFESSOR) Ravindra Pathak Rishabh Bajpai 14/04/2016
  2. 2. CONTENTS Objectives Working Main Features Hardware Used Software Used Microcontroller PIR Sensor Relay Block Diagram Circuit Diagram Application 14/04/2016 1
  3. 3. OBJECTIVE  This project will deal with a system which will provide a Automatic room appliances controlling system  If any person will enter in the room then this system will detect his entry and automatically turn on the lights and fans  One more feature is that, this system will not turn on the light in day time it will on the light only in night time or when there will be not enough light in the room 14/04/2016 2
  4. 4. WORKING  PIR sensor will be first installed on the roof of the room  PIR sensor will detect the reflected rays from surrounding material  If there will be any change in transmitted rays then PIR sensor will detect this change and give signal to microcontroller  Microcontroller will activate the relay and relay will turn ON the room appliance 14/04/2016 3
  5. 5. MAIN FEATURES  PIR based sensing  Temperature based sensing  Auto Light controlling  Auto Fan controlling  Microcontroller ATmega16 14/04/2016 4
  6. 6. HARDWARE USED  Microcontroller ATmega16  PIR Sensor  12V Relay  Appliances 14/04/2016 5
  7. 7. SOFTWARE USED  All the software developed for this project will be loaded into the memory of the ATmega16 microcontroller  The language must be supported by the ATmega16 compiler  The ATmega16 compiler supports C and Assembly  Reasons for Selection C Programming Language  Vast amount of online resources  Ease of development  Team members have experience of coding in C 14/04/2016 6
  8. 8. MICROCONTROLLER  The ATmega16 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle  The ATmega16 achieves throughput approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed 14/04/2016 7

  10. 10. PIR SENSOR Operating principle: • All objects with a temperature above absolute zero emit heat energy in the form of radiation. • Usually this radiation is invisible to the human eye because it radiates at infrared wavelengths, but it can be detected by electronic devices designed for such a purpose. 14/04/2016 9
  11. 11. • The term passive in this instance refers to the fact that PIR devices do not generate or radiate any energy for detection purposes. • They work entirely by detecting the energy given off by other objects. PIR sensors don't detect or measure "heat"; instead they detect the infrared radiation emitted or reflected from an object. PIR SENSOR 14/04/2016 10
  12. 12. RELAY  A relay is an electrically operated switch  Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relay  Relays with calibrated operating characteristics and sometimes multiple operating coils are used to protect electrical circuits from overload or faults; in modern electric power systems these functions are performed by digital instruments still called "protective relays" 14/04/2016 11
  13. 13. 14/04/2016 12 Distribution Of Work into 6 Module: • Module1: Selection and Purchasing of components • Module2: Prototype PCB designing • Module3: Mounting of components on PCB • Module4: Hardware Testing and Final PCB designing • Module5: Firmware coding • Module6: Testing of Complete System
