Product 3: Keep in Touch

A parent will get a home device that s/he will activate with the fob they get from the park Sign Up station. This, therefore, means that only people in the system are aware of the system. The home device will activate with the fob, then it IFTTT’s the parent an email link to register the device.

This device will communicate ambiently via three colors: Green to indicate a chaperone present and alert, yellow for a chaperone at the playground but not alert and red for having no chaperone present.
