UNO R3 Smart Environmental Monitoring Kit | Arduino STEM IoT Learning Set with Temperature, Humidity, Light & Gas Sensors | Includes DHT11, LDR, MQ-2 & Relay Modules for Smart Home Automation & Environmental Science Education

The UNO R3 Smart Environmental Monitoring Kit is a comprehensive STEM educational platform focused on IoT-based environmental data collection, analysis, and automation control. Built around the UNO R3 microcontroller, it introduces students to the principles of digital sensing, cloud connectivity, and intelligent response systems.

The kit integrates essential sensors, including the DHT11 temperature and humidity module, LDR light sensor, and MQ-2 gas sensor, enabling learners to monitor atmospheric conditions and detect environmental changes. Through programmable logic, users can automatically control outputs such as relays, fans, or alarms when specific thresholds are reached — simulating real-world environmental management systems.

Equipped with an LCD 1602 display, the system shows live readings of temperature, humidity, light intensity, and air quality. Students can also upload real-time data to cloud platforms using the optional Wi-Fi communication module, demonstrating how modern IoT systems store and visualize information remotely.

With support for Arduino IDE, Mixly, Scratch, and Python, this kit accommodates both text-based and graphical coding environments. Students can progress from simple data logging projects to advanced IoT automation experiments, learning about sensor calibration, analog signal processing, and cloud-based control.

The modular structure allows for plug-and-play assembly via breadboard and jumper wires, requiring no soldering, while the safe 5V USB power supply ensures reliable classroom operation. Designed for schools, labs, and maker education programs, this kit bridges the gap between environmental science and modern IoT engineering, preparing learners for future technologies in sustainability and automation.
