How to efficiently control relays

Relays are incredibly useful and are utilized in nearly every automation system due to their ability to control a high-power circuit with a low-power signal. However, the traditional approach to relay operation is relatively energy-intensive, potentially generating excess heat and requiring a sizeable power supply to operate. This raises the question: might there be a better way; an approach to efficiently control relays?

Turns out, there is. Let’s dive deeper into the world of relays to uncover the smart and efficient way to control them.

Exploring Centralized IoT Approach vs. Standalone Devices

IoT systems vary widely, ranging from simple tasks like changing your living room light color via your smartphone to monitoring and controlling multiple buildings. The vast array of IoT applications and the varying complexities of their integration raises many questions about the best approach to development.

Two main approaches can streamline the development of these varied IoT systems. The first uses a central command unit that interfaces with all peripheral devices and manages the IoT functionalities of the application. This central hub manages all communication and data processing across the network. The second approach involves using independent smart devices, where each is dedicated to performing simple tasks and equipped with its own IoT capabilities, allowing for decentralized operation and direct communication with user applications or cloud services.
