Our device will indicate when your dog/pet wants to come back inside from playing, defecating, or laying around. Our device will help any individuals that have a busy schedule and can't watch over their dog being outside. The device works by using a motion sensor to detach any movement near the door. If there is movement an ultrasonic will turn on and double-check if there is actually a dog at the door. When both sensors indicate that there is a dog at the door, the sensors will then send that information to the third device which is a passive buzzer. The buzzer will sound indicating that you must let your dog in. Understanding how the Particle Argon and sensors operate we’re able to make this device come to life.
Figure 1 shows the motion sensor configuration with our first Particle Argon.
Figure 2 shows the ultrasonic sensor configuration with our second Particle Argon.
Figure 3 shows the passive buzzer configuration with our last Particle Argon.
Figure 4 shows all the sensors together. The active buzzer can be relocated and placed anywhere as long as the Particle Argon is connected to WiFi. The motion sensor and ultrasonic sensors must be together at the door.
The video above shows a live demonstration of our device functioning in real-time.
