About the IoT-based home automation wiring diagram

The following wiring diagram is a guide to how a smart home system can be implemented utilizing IoT technology. IoT makes regular appliances and devices smart. It allows them to get connected and interact with each other. So that you can manage different aspects of your home surroundings.

Here, the wiring diagram of IoT-based home automation will explain the working of normal IoT home automation. The system links several electrical systems with Wi-Fi technology for distant control. The system is operated by a battery connected to the microcontroller. The ultrasonic sensor sends an output signal to the microcontroller.

The power operating the household appliances is a 220V AC so a circuit breaker has been installed for safety reasons. The Node MCU ESP32 is connected by a Micro USB cable and can transmit data to the user interface, for example, a smartphone or a tablet.

This microcontroller accepts inputs from the user interface/sensors and outputs control signals to a 4-relay Interface Board. Each relay on the module functions like a switch controlled by the microcontroller to turn devices connected to the module 'On' or 'OFF.' The inputs of the relay module are connected to the GPIO pins of ESP32.

The circuit includes a fan, two bulbs, and a TV where all these appliances are connected to the relay module. Every relay has Normally Closed, (NC) terminals, and the Common,(C) terminals regulate the flow of electricity from the 220V AC supply to the appliances.

Whenever a user types a command in the interface, this command will be routed to the Node MCU ESP32 board. Depending on whether the relay should be turned on or off, the relay will be triggered on the module. This activation enables to switch on or off the appliance.
