Many dog owners face the problem of their dog breaking, damaging, or otherwise interacting with an object or area they shouldn’t. Additionally, owners with multiple dogs may have trouble keeping one dog from eating the other’s food.
Our solution is to create a bluetooth-enabled collar system that will spray the dog in the face with citronella spray when the dog approaches the object or region of interest programmed by the user. This spray has been tested and is completely harmless to the animal, with multiple products using this spray already in production.
Our product will be unique in that it allows distance sensitivity to be configured by the user via a free mobile app. Existing products that are most similar implement a similar spraying collar that detects barking rather than distance, or a remote control that triggers the spray. The first product offers a solution to a different problem completely, while the second is inconvenient (when the user is not with the dog, it is completely ineffective).
1. Sensor(BLE) Subsystem:
The RSSI values from the Bluetooth Low Energy controller(nRF52832) will be used to indicate the distance between the dog and the sensor. When the RSSI value is less than the desired range, the controller will signal the spray to stop the dog. Both the sensor and the collar’s bluetooth device will be on, so that they we automatically connect when the dog enters the connection range.
2. Spray Subsystem:
For the spray that will be activated after it receives a signal from the BLE controller, we will use a mini 12V water pump with a short thin tube for a spray effect.
3. Power Subsystem:
Since all subsystems will be connected to a power source at all times, we plan to use a rechargeable lithium ion battery that can be charged via a micro USB cable.
4. User Interface:
The user interface(app) will be used to program the controller to set the desirable distance.
Criterion for Success:
Since we cannot test the effectiveness on an actual dog, the goal would be to accurately activate the spray at the desired distance.
