This is the second part of home automation without using a microcontroller. In the previous part, we have designed a remote controller using RF module. And again if you do not have RF module on Proteus you can download from this link Rf module electronify Now in this section we will connect the necessary home appliance to the receiver side and the remote part will be left as it is. For this demo, we are going to turn on fan and light only but you can connect other devices as well. and complete proteus file can be downloaded from this link home automation without using microcontroller electronify.
Now we have disconnect two led from previous circuit diagram and now then these two pins are used to trigger the relay. If D9 of the transmitter is on then Lamp point of receiver section goes to high and this high signal is connected to the transistor and transistor is turned on ( remember transistor is used as a switch in this project ). And similarly, another pin of a transmitter is used to trigger fan by using an appropriate connection.T hat’s all concept behind this project. If you have any question about this project please leave a comment below, I will try to solve your problem.
