The radio frequency rf remote control circuit has wide range of applications and we have been using this in our daily life.
Rf remote control schematic.
Limitations of the circuit.
The basic small range remote controls are 2 infrared and rf radio frequency.
The use of the ready made rf module simplifies the construction of a wireless remote control system and also makes it more reliable.
One of the weaks of infrared is that the signal can not pass the walls.
Used for remote control applications like burglar alarm car door alarm calling bell security systems etc.
Rf remote control circuit designed with 434 mhz ask amplitude shift keying transmitter and receiver here ic ht12e act as encoder and ic ht12d act as decoder this circuit is constructed with easy available components.
Works for longer distances as compared to ir.
The circuit transmitter and receiver use few components and ordinary i love few component circuits.
Rf remote control circuit advantages.
Building a hi end remote control device using very few components today looks pretty plausible.
The proposed remote control light switch circuit idea provides you with the opportunity of building and owning this amazing device through simple instructions.
Rf remote control circuit applications.
Rf signals can travel even there is an obstruction between transmitter and receiver.
This remote gives approximately 150 meter coverage by extending the ariel wire it can be increased up to 200 meters.
And its important for electronics engineers and hobbyist to understand the operation of rf based wireless remote control to achieve long distant communication.
This project has two stages that is 1.
