Final Project - System Design(Electronics)
Essential function of the cat shelter
Some essential functions are listed of my final project - cat shelter as below:
- Getting the position data of cat shelter
- Detect whether a cat get in the shelter
- Detect the remain food and water by weight or level
There's a list about the sensors to satisfy the function which listed
| Sensor/Microcontroller | Function | Price | Count | Link |
|---|---|---|---|---|
| XIAO ESP32C3 | Controllers for getting sensor data | 9.99 | 2 | link |
| RYS352A GNSS Antennia | Getting position data | 10.00 | 1 | link |
| HX711 load cell sensor | Sensing remain cat food | 6.79 | 1 | link |
| WWZMDiB 12 Water level sensor | Sensing remain water | 6.99 | 1 | link |
| HC-SR501 PIR sensor | Detect the cat inside the shelter | 8.49 | 2 | link |
Here's the designed system in block diagram.
In cat shelter side, many sensors are connected to the microcontroller and send the sensing data to the user side through ESP-NOW protocol. It simulate there's a central control station of the cat shelters.
A website-based web server will be built in user side, which is used for showing the sensing data or status of the cat shelter. I can refer week 11 assignment to build up a web-server for showing the sensing data in a user interface.
It's a sample that showing the position data in a website which's web server is uploaded in a Microcontroller.
