This use of this device is not meant for conventional living environments, it is more for an apartment or residence hall setting where there is limited kitchen space shared among room mates. The data gathered by this device can be used to track trends in kitchen usage. This device's purpose was to remotely sense a kitchen's occupancy, and exhibit communication between 2 Particle Photon devices.
For this particular project the device senses the occupancy in a kitchen, however with the variable range of the PIR sensor it can be adjusted for other types of rooms as well. Upon noticing broad movement in the kitchen the PIR sensor on the sensing photon communicates to the notifying photon through a publication. Once the second photon receives the publication, it notifies the user through a text notification using IFTTT, and IFTTT will track the time and event and promptly add it to a google sheet. The google sheet is formatted so that any new event is recorded and immediately graphed showing times where the kitchen is occupied since the device was first implemented.
The data for the graph above was gathered from a test session where we tested the time tracking capabilities of the photon in an engineering computer lab for around 5 minutes. Click here to see the live graph.
