The combination of the BCTLABSUNO CH340, BCTLABS Power Distribution Board, and BCTLABS 4-Port Connector creates a highly efficient and reliable system that outperforms traditional setups built with a generic Arduino UNO. In this project, the ultrasonic sensor is connected via the 4-Port Connector, which not only reduces wiring complexity but also ensures stable data transmission by providing secure screw-terminal connections. The soil moisture sensor is directly integrated with the controller, feeding accurate real-time readings without requiring additional interface boards.

For powering the system, the BCTLABS Power Distribution Board plays a crucial role. It accepts a 12V DC input and distributes power through onboard regulators, supplying consistent 5V and 3.3V outputs to sensors, modules, and the relay. This eliminates the need for multiple external power regulators and adapters, a common issue with generic Arduino setups. The regulated and filtered outputs also protect the sensors and controller from voltage fluctuations, improving the system’s lifespan and reliability.

The motor pump is controlled through a 1-channel relay connected to the BCT UNO CH340. Unlike the generic UNO, which has limited current handling and often requires external driver circuits, the BCT UNO CH340—with its higher current capacity and multiple power access points—manages sensor inputs and relay operations smoothly without performance drops.

Overall, this integrated design ensures stable power distribution, cleaner wiring, and robust performance under load. Where a generic Arduino UNO setup might suffer from unstable readings, frequent resets, or wiring issues, the BCT ecosystem guarantees professional-grade efficiency, safer operation, and long-term stability, making it the ideal choice for smart irrigation, water management, and automation applications
