Chinese STEM education provider DFRobot showed an IoT-enabled smart city offering at last week’s Bett education show in London.

This blended smart city design with IoT technology to show students and teachers how to monitor and instruct smart city intelligent systems by combining the knowledge and skills from programming, hardware control, data acquisition and IoT platforms, helping promote IoT education in schools.

The demonstration showed how camera and agricultural sensors installed in a farm can observe the growth of plants in real time. The housing area measured temperature, humidity and carbon dioxide conditions. The weather station can help students understand the atmospheric motion state through wind speed, direction, temperature, humidity and pressure. Water quality sensors such as pH and TDS were installed in the lake to facilitate timely understanding of water quality and the living environment of fish. An IoT server can interact with other microcontrollers through wireless local networks. All the data collected were shown on the monitoring screen in different forms such as line chart and bar chart.

This project also showed visitors how to make an earthquake shake table using a Boson kit to simulate earthquakes at different frequencies.

Using the Maqueen Plus and Maqueen Mechanics – AI-enabled robotics kits – visitors saw how the products worked in an intelligent transportation display. This demonstrated automatically tracking the line through greyscale sensors. With an AI machine-vision sensor, it recognised colours and objects, and performed corresponding actions.

“We are incredibly excited about our offering this year at Bett, from innovative products to creative displays,” said Ricky Ye, CEO of DFRobot. “Our products are designed to inspire and motivate young minds to explore the fascinating realms of science, technology, engineering and mathematics. We believe our dynamic and innovative products do just that, offering students and teachers an exciting world of coding, programming and AI.”
