Cordless
Power Controller | This
project Cordless Power Controller (CPC) is essentially a remote control implemented
with the help of a cordless telephone. It has been developed as a standalone device
as per the conventional DOT standards. Connecting CPC to the telephone line makes
it possible to control lights, fans and other appliances of our home using our
cordless phone.The interesting
feature of CPC is its ability to control two types of devices; they are ON/OFF
control and ON/OFF with speed/intensity control.CPC is developed as a microcontroller
8051 based device. Which controls the devices depending on the codes entered through
telephone keypad. Intensity or speed variation is obtained by altering the phase
of the gate pulses given to the triac for triggering it.
