The input signals at the transmitter section are taken from the four switches and the output signals at the receiver are indicated by the four LED's corresponding to each switch.Ĭircuit Diagram of Remote Control Circuit Through RF Without Microcontroller When we press any key in the remote, the transmitter section generates the corresponding RF signal and this signal is received by the receiver section, hence it switches the corresponding appliance.Ī four channel encoder/decoder pair is used in this system. At transmitter section, we use HT12E encoder and at receiver section, we use HT12D decoder. This project has two sections, one is transmitter section and the other is receiver section. Using this remote, we can control the appliances within the range of 100 meters.

Here we have used RF434 MHz modules to make wireless remote. But, have you ever tried to design wireless communication circuit without any microcontroller? This article explains you how to control the home appliances wirelessly using RF technology.

We have already learned in earlier post about how design IR Remote Control for Home Appliances.
