UNO R3 Intermediate Sensor Expansion Kit | Advanced Arduino STEM Learning Set with Ultrasonic, Temperature, Light & Sound Sensors | Programmable IoT Education Kit with Breadboard, Relay & RGB LEDs | Ideal for Teaching Automation & Logic Control

The UNO R3 Intermediate Sensor Expansion Kit is designed for learners and educators who want to move beyond basic Arduino experiments into real-world sensor control, automation, and IoT simulation. This kit builds upon the foundational starter kits by integrating multiple sensors that respond to environmental changes and trigger corresponding electronic actions.

Powered by the UNO R3 board, the kit supports a wide variety of experiments — from ultrasonic obstacle detection and temperature/humidity monitoring to sound-activated systems and flame detection alarms. Each sensor connects easily to the Arduino via the included breadboard and jumper wires, allowing quick setup and safe experimentation without soldering.

The kit introduces students to signal processing, conditional logic, and sensor fusion, helping them understand how data is captured, interpreted, and used to control outputs like LEDs, buzzers, and relays. With RGB LED modules and a joystick, learners can explore human–machine interfaces, motion detection, and interactive control design.

This educational platform is fully compatible with Arduino IDE, Scratch, and Mixly, accommodating both textual and graphical coding approaches. Teachers can guide students through progressive challenges, from simple sensor readings to complex automation projects involving multiple modules.

Operating at 5V USB power, it is safe for classroom use, while all components are modular and reusable. This kit bridges the gap between theory and application, empowering students to design, build, and test their own smart systems and IoT prototypes.
