Required Components for the Smart Relay Module PCB:
1. Relays 5v (SPDT) (8 no)
2. BC547 Transistors (8 no)
3. PC817 Optocuplors (8 no)
4. 510-ohm 0.25-watt Resistor (8 no)
5. 1k 0.25-watt Resistors (10 no)
6. LED 5-mm (10 no)
7. 1N4007 Diodes (8 no)
8. Push Buttons (8 no)
9. Terminal Connectors
10. 5V DC supply


------Important points for this ESP32 project:------
1. IR receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code.
2. After compiling the code, you have to press and hold the BOOT button of ESP32 until the code starts uploading.
3. No need to install BluetoothSerial library separately in Arduino IDE.
4. You can use any IR remote for this project.
5. First you have to pair the ESP32 with Mobile Bluetooth, then connect ESP32 with Bluetooth App.
6. Please take proper safety precautions while working with high voltage.

During the tutorial video, I have explained all the steps to make this home automation system, how to program the ESP32, how to connect mobile Bluetooth with ESP32 for this home automation solution.
In this ESP32 project, you can use any IR remote, just get the hex codes of unused IR remote buttons, and control the appliances with those buttons.
This smart relay module can be used for different ESP32 projects which I will cover in upcoming videos.
