32 channel smart home automation DIY relay controller module Circuit Diagram Industrial Automation: Control motors, solenoids, and actuators. Automotive Systems: Manage lighting, sensors, and other high-side loads. Home Automation: Build smart switches for appliances and lighting. Conclusion. The VNI4140K is a versatile and reliable component for building smart power relay systems. The circuit is very simple, we just need a Nodemcu board and a relay module to control home appliances securely from the smartphone through the internet. I have shared all the details like esp8266 NodeMCU pinout, circuit, Arduino sketch, Blynk App setup for this smart home project.

In this home automation project, we will design a smart home relay module that can control 5 home appliances. This relay module can be controlled from Mobile or smartphone, IR remote or TV remote, Manual switch. This smart relay also can sense the room temperature and sunlight to turn on and off the fan and light bulb. This smart relay has the

Smart Home Automation System Using Arduino: A Complete Guide Circuit Diagram
If you want, you can also use this PCB to make the circuit compact and give the project a professional look. This PCB can be used for any ESP32 Home Automation project. Connect Home Appliances with Relay Module. Connect the home appliances with the relay module as per the circuit diagram. Now, turn on the 5V DC supply and 110V/220V AC supply. Relays play an important role in automation circuits. Whether it's industrial or home, the type of relays can change but the principle remains the same. You may already know that relays in home automation are devices that activate another appliance. This might be anything from a light bulb to a motor. Smart home automation can be used in a A relay lies at the heart of this project, acting as an electronic switch that is controlled by an Arduino. As electrical switches, relays open and close based on digital signals received from a computer or microcontroller board. This makes them ideal for DIY home automation, as they work well with Arduinos and other basic boards.

Working of Arduino based Home Automation. Make the connection for Home Automation project as given in the circuit diagram. First of all, we connect the bulb with AC powered sources and with relays as given in the circuit diagram. Then the relays are given DC power from the Arduino Uno board. So, in this tutorial we are going to learn about home automation using Arduino, Relay and Bluetooth Module. Here, we have automated our four room appliances namely AC, Bulb, Heater, Fan. Let's get started with the today's tutorial. Components Required: Arduino UNO X 1; 5 Volt Relay Module X 4; HC-05 Bluetooth Module X 1 To build a smart home automation system using Arduino, you will need the following components: Circuit Diagram. Connect the VCC pin of the relay module to the 5V pin on the Arduino board
