Why choose complex when you can always switch to simplex..!! Just like your personal computer, switch your home appliances on/off just at the click of a button. All we need here is a wireless device that performs your switching operations. The IR Remote Switch available at Multyremotes.com may prove your best search. An IR Remote switch is a remote control which can switch on/off any electric appliance, be it AC OR DC like fan, table lamp, tube-light, bulb, etc.
It is a sound, engineering product which bears a transmitter and a receiver. The transmitter unit is integrated on the remote control and the receiving unit is fixed at the appliance under control. The operating range of this switch is around 10 metres. The remote bears its name after the infrared (IR) sensors used to detect the signals of the transmitter at the receiving unit. This is what that substitutes the use of wires in the system. The remote control also bears a red Led for convenience which glows whenever the user pushes the button to switch the appliance on/off. Grab it for an easy and handy experience with your home appliances and that too, economically.
Whenever an input signal is given to the remote, it generates a continuous wave pulse with the help of pulse generator (a multivibrator) which switches on the IR led. The IR signals hence generated by the led are detected by the sensor at the receiving unit. The sensor then intimates the device to alter its current state of operation accordingly with the help of a J-K flip-flop. Thus every alternate time the switch is pressed, the appliance turns on or off.
Hobbyists can try making up this project for them or even purchase it from Multyremotes.com. It is all about learning and exploring the unlearned.
