Project name

Pet Fit Collar for Cows

Description

The Pet Fit Collar is a wearable health and activity tracker designed for cows. It monitors vital parameters like heart rate, body temperature, and movement.
The project aims to help farmers and veterinarians remotely monitor cow health in real time, improving animal welfare and early detection of health issues.

Special part: It combines multiple sensor readings into one lightweight collar system powered by an Arduino.

Functions

Measure cow’s heart rate using a heart rate sensor.

Monitor body temperature with a temperature sensor.

Detect movement and distance using two ultrasonic sensors.

Display collected data on a serial monitor or send to a connected device for further analysis.

Hardware and Software Used

Hardware:

Arduino Uno (or any Arduino-compatible board)

2x Ultrasonic Sensors (HC-SR04)

1x Temperature Sensor (DS18B20 or LM35)

1x Heart Rate Sensor (e.g., MAX30100 or pulse sensor)

9V Battery + Battery Clip (for portable power)

Wires, Connectors, and Collar Mount

(Optional) Bluetooth Module (like HC-05) for wireless data

Software:

Arduino IDE

Libraries for sensors (like OneWire and DallasTemperature for DS18B20)

(Optional) Serial Bluetooth Terminal app for mobile viewing

Wiring Diagram

(Diagram should be drawn separately — I can help you make a basic one if you want!)
Key connections:

Ultrasonic sensor 1: Trigger → D2, Echo → D3

Ultrasonic sensor 2: Trigger → D4, Echo → D5

Temperature sensor: Data → D6 (with a 4.7kΩ pull-up resistor)

Heart rate sensor: Signal → A0

All sensors powered via 5V and GND pins on Arduino

Code

Summary:

Read temperature, heart rate, and distance values.

Print values to the serial monitor.

(Optional) Send values over Bluetooth for mobile monitoring.

Printing Instructions

(If 3D-printed casing/mount for sensors is used)

Filament Material: PLA

Layer Height: 0.2 mm

Infill: 20%

Supports: Yes (for sensor mountings)

Assembly Instructions

Attach sensors firmly onto the collar.

Connect sensors to Arduino as per wiring diagram.

Place Arduino and battery securely in a waterproof pouch on the collar.

Upload code to Arduino via Arduino IDE.

Power the setup with the battery and start monitoring.

Demo and Usage Instructions

Power on the Pet Fit Collar.

Connect via serial monitor (or Bluetooth app) to view live health data.

Monitor temperature, heart rate, and movement patterns.

Alerts or data logs can be added later for enhanced functionality.

Additional Notes or Tips

Ensure the collar is comfortable and doesn’t irritate the cow’s neck.

Waterproof the electronics properly before use in real environments.

Future enhancement: add GPS tracking, solar charging, or IoT data upload!
