The STEM Module: Internet of Things For A Sustainable Future is an initiative by the UniKL BMI STEM Committee that uses IoT technology as an innovative learning approach to enhance student engagement in Science, Technology, Engineering, and Mathematics (STEM). This program aligns with national priorities such as advancing TVET and adopting Industry 4.0 (IR 4.0), while also supporting the global Sustainable Development Goals (SDG). By focusing on IoT's transformative potential to address crises like climate change and resource depletion, the module prepares students with crucial skills, directly impacting each STEM element: applying Science to environmental problems, building expertise in Technology like sensor networks and cloud platforms, using Engineering for designing sustainable systems, and enhancing Mathematics skills for data analysis and informed decision-making. The overarching goal is to inspire a new generation of innovators to use technology as the building blocks for a resilient and sustainable future.
