The #GOALS SACS exhibit was designed to introduce middle school students to healthcare careers by incorporating art, computer science, and data science.
The exhibit consists of a motion sensor network of Raspberry Pi 400 computers and PIR sensors laid out in a gallery format. The art in this gallery consists of eight large displays of healthcare careers including:
- Doctor
- Dentist
- Physician’s Assistant
- Dental Hygienist
- Pharmacist
- EMT
- Medical Assistant
- Nurse Practioner
Participants browse the gallery of healthcare careers eight Pyroelectric Infrared PIR Human Sensors placed throughout the exhibit. The triggered sensors continuously generate timestamped event data which is stored as flat files on the Raspberry Pi devices. Splunk forwarder software installed on each Rasbperry Pi monitors the data generated by the PIR and periodically forwards the event data to a main device (Macbook Pro laptop computer). The data is indexed and stored in Splunk format. Splunk Search Processing Language (SPL) code is used to convert the event data to visualizations in a dashboard on a large display screen.
The setup includes the following components which can be found on Amazon for use in classroom activities after the event:
