Abstract: This paper implements an IoT system for environment monitoring and remote web control using ARM Mbed cloud. The embedded system used for environment monitoring is implemented using an ARM Cortex-M4 core-based STM32L4 series development board integrated with multiple sensors. The sensed data (i.e., temperature, relative humidity and atmospheric pressure) can be wirelessly sent to the Mbed cloud managed by the Pelion device management platform. The data values can also be sent to a Graphical User Interface (GUI) with user authentication. We develop three application appliances that can be controlled remotely over Internet through the Pelion platform. The proposed IoT system has been successfully implemented on the STM32L4 series development board with the main application program developed using C++ and the GUI developed by C# programming. The work of hardware and software co-design can be a practical paradigm of engineering education for IoT hobbyists and college students.
