4. Abstract
 Reduce electrical energy consumption
in academic institutions.

5. Introduction
 Use of sensors and microcontroller
 proposed energy saving system
(PESS)
 proper power management system
(PMS)

6. Proposed Work
1. Chair in the cabin is free
2. Chair in the cabin is not free

7. System Hardware Description
 PMS (Power Management System)
 proposed energy saving system (PESS)
 Sensors
 Microcontroller

8. System Operating Functions

9. Control System for Lighting and
Ceiling Fan
 For light LDR is used
 For Ceiling Fan LM-35 used

10. Student Detection System
 The Ultra-Fire remote pressure switch is used as a sensor.

11. Results and Discussions
 UET library’s contains 22 cabins while
Hazara University library’s has 32
cabins.
 when there is no one inside the cabin,
the energy consumption per hour in this
case is calculated as 22×4=88Wh.
 When the cabin is occupied, the energy
consumption of cabin is 128Wh

12. Cost Analysis
 When electricity price is 32Rs/unit, the bill in UET library is
Rs147680, but when using PESS it is Rs87840 UET save
29.34% of total bill.
 In Hazara University it is Rs247200 and by using PESS it is
Rs149760. Hazara save 29.70% of total bill.

13. Conclusion
 The paper presented the energy saving strategy in
libraries using the power electronics converters and
microcontroller.
 From the results, it is concluded that the proposed
energy saving system is cost effective.
