Description
The electronic circuit design like in Figure 1 above show you RF based home automation circuit using 8051 IC.
According Electronicshub blog mentioned that the main component of the RF based Home Automation is the RF Module. An RF Module is a small electronic circuit which is used to transmit or receive data wirelessly.
RF Modules are often used in consumer applications where you need to remotely control some machines or appliances without making any physical contact with them.
Some of the common applications are wireless alarm systems, garage door openers, industrial remote controls, wireless home automation systems and smart sensor applications.
RF modules do not require line-of-sight operation. Hence, they are often used instead of infrared remote controls.
Depending upon the type of application, the RF module is chosen.
For example, in case of short range wireless control applications, we can use ASK modulated RF Module of frequency 315 MHz or 433 MHz.
