This work presented here is to controlled independent home electrical appliances through RF based remotesystem. From any place without any line of sight around the house, RF based wireless remote control system can change the state of the electrical appliances either in on state or off state. The controlling circuit is built around RF transmitter and RF Receiver modules and decoder IC HT12D with few passive components. The four different channels at the encoder are used as input switches and the four channels at the decoder output are connected to the appliances through a relay.. The main objective of this work is to build the circuit without any programming skill and to make it work without line of sight requirement using the RF technology
- The main objective of this project is to control home appliances by using RF technology, which helps to turn the electrical loads such as light, and fan ON and OFF through an RF-controlled remote.
- This is an advanced technology for home Appliances Control as it is used to make homes very smarter without requiring any switches on the walls.
- RF transmitter receiver module
- Encoder and decoder ic
- voltage regulator
- relay driver ic
