Abstract:

Now-a-days there is lot of devices operated by a RF remote control at houses, televisions, AC’s, VCR’s, heating systems etc., In addition the expected wide spread of technology at home will reveal a new world of opportunities. The main objective of this project is to use radio frequency band. The appliances are controlled by the RF transmitter by pressing a specific switch on the transmitter and it produces specific signals which propagate through air. This project makes use of transmitter (TX-2B module) and receiver (RX-2B module). At 433MHz that is available at low cost hence making it very compact. The RF based control proves to be more advantageous compared to IR based control that limits he operating range to only few meters of distance. This is designed with AC supply, Rectification circuit, and transmitter with remote, receiver circuit and relays mainly. By using the remote, we can control the switches and receiving circuit. The rectified voltage is regulated by regulated by LM 7805 to 5V. The receiving circuit is used for operating of relay switches which are used to select electrical appliance for operation. This project can be implemented for commercial & business offices by using long range RF transmitter and receiver.
