How to Interfacing Relay Module with ESP32
In this Article, we learn about How to Interfacing Relay Module with ESP32. In the Last post, we learned how to add Arduino Uno Library in Proteus. I hope you appreciate my work,
Let’s Discuss about Today project.
Interfacing a relay module with an ESP32 is a common task in IoT projects. A relay module is used to control high-power devices using a microcontroller like the ESP32.
Components Require:
- ESP32 development board
- Relay module
- Jumper wires
- Power supply (if needed)
Circuit Diagram:
Operating Principle:
When you run code on the ESP32 that sets the GPIO pin connected to the relay to HIGH, the relay receives a signal, and its internal switch closes the circuit, allowing current to flow to the high-power device. Conversely, setting the GPIO pin to LOW de-energizes the relay, opening the circuit and cutting off power to the high-power device.
This process enables the ESP32, through its GPIO pins, to effectively control high-power devices by using a relay module as an intermediary switch, making it safe to interface low-voltage microcontrollers with high-power electrical appliances.
