This research proposes the Design and Development of Automated Switching for Energy Saving System (ASESS) prototype. The main motive of this research is to reduce the domestic energy consumption and power demand. This project has two systems which are Indoor Environment and Outdoor Environment systems that use only one power supply. The first system has built-in visitor counter in which its function is to count the exact number of persons entering and leaving the designated premises. Visitor counter is displayed on Liquid Crystal Display (LCD) and the program is executed using a microcontroller where its software utilizes Arduino Uno. Two infrared sensors were used to detect the movement of the people who are entering or leaving the premises. Basically, when someone passes through the infrared sensor, the system adds the visitor counter while the other sensor subtracts from the counter every time it detects human movement. When the visitor counter displays positive number, the appliance is automatically switched on, while it automatically switched off when the visitor counter displays zero. Furthermore, red LED is automatically switched on if the temperature of the room exceeds the maximum temperature setting as temperature sensor was used in this system. Besides that, present of people and temperature in the room can be monitored from smartphones based on Internet of Things (IoT). Moreover, the second system composes light intensity optimization technique by applying light dependent resistor (LDR) sensor where sunlight is involved. When light intensity decreases, the appliance such as bulbs will switch on and vice versa when light intensity increases.
