Introduction
This relay module features a premium Omron relay enclosed in a fully transparent case, letting you clearly observe contact movement—turning an abstract component into a visible learning tool. It uses a Gravity interface for easy digital control (just HIGH/LOW signals—no I2C or serial needed) and includes DC2.1 jacks for direct power input and load output, greatly simplifying wiring. Specially optimized for inductive loads like motors and water pumps, its contacts offer longer lifespan than standard relays. Perfect for education, prototyping, and reliable switching in maker projects.
Features
Fully transparent relay, view contacts state at a glance
Quality Omron relay, contacts with longer lifespan
Output can be directly connected to VCC load, like water pump, or servo, etc., without externa power source, easy to use
Applications
Auto watering system
Auto control
IoT controlling system
