Story

Well the story is, we love our snacks. But apparently, we live with room mates who also love OUR snacks. So we had to come up with a solution. Our solution was to utilize two Particle Argons as a security alarm. One Argon was set up with a PIR sensor.

PIR Sensor and Particle Argon

Additionally, Argon One was also set up to send us an email notification whenever the sensor is tripped.

Email Notification From Argon One

The other Particle Argon was set up with an LCD display to notify us physically when the sensor has been tripped.
