Time Operated Electrical Appliance Controlling Systems by Using Microcontroller
Awadallah Sulieman Rahama, Dr. Dalia Mahmoud
Abstract: Time operated electrical appliance controlling system is a reliable circuit that takes over the task of switch on/off the electrical devices with respect to time. The operator may not be at place and may be somewhere in a different place and if the necessity arises to control these different appliances there must be some source to control and monitor the different appliances. This idea replaces the Manual Switching to automatic switching. The devices at home like electrical light, electric fan, air conditioners are needed to control so using the microcontroller of this process and there are two relays to control in buzzer and fan at a certain time. When this time equals to the programmed time, then the corresponding device is switched ON and at the end of time the device is switched OFF and the switching time can be edited at any Time using the keypad and the instructions are displayed on LCD display.
