Problem solving challenge: using computational thinking and the Internet of Things to improve fire safety
This five hour teaching pack examines how everyday technologies can be connected via the Internet Of Things (IoT) to improve fire safety.
From the sensors that detect heat and gases; through the connected computers that read and shape data shared through the cloud; to the networked end-user devices presenting information to users or communicating with other smart devices – students will design their own solution to a problem of their choosing. A simplified model of this fast-moving area of innovation helps students to grasp it as a whole.
The project can be used to support students in gaining Discovery CREST accreditation or could be extended to prototyping of solutions for students aiming at higher CREST Awards. It requires no specific equipment or programming knowledge and, instead, focuses on data, the network protocols that carry the data, and the algorithms that handle it. The differences between analogue and digital data in the context of the devices, such as Raspberry Pi, that can input and process this data. Modern wired and wireless protocols are investigated, and information sheets are provided to get students started on deeper research tasks.
It is recommended that, prior to this activity, students have been introduced to the Internet of Things using this introductory computing activity.
