DOG BAND

1. Project Objectives

1.1 Location Tracking:

• Utilize a GPS module to capture real-time coordinates of the dog’s location.

1.2 Pulse Rate Monitoring:

• Integrate a pulse rate sensor to measure the dog’s pulse in real-time, promoting health monitoring.

1.3 Remote Monitoring:

• Implement Blynk IoT software to enable users to remotely monitor their dog’s location and health data.

1.4 Alert System:

• Develop an alert system for notifying users in case of predefined events, such as the dog leaving a designated area or experiencing abnormal pulse rates.

1. Technologies Integrated

2.1 NodeMCU:

• Serves as the central processing unit, responsible for data processing and communication among hardware components.

2.2 GPS Module:

• Captures real-time location data, enabling accurate tracking of the dog’s movements.

2.3 Pulse Rate Sensor:

• Measures the dog’s pulse, providing essential health-related information.

2.4 Blynk IoT Software:

• Creates a user-friendly interface for remote monitoring, enhancing accessibility for pet owners.

1. The Dog Band project is versatile, allowing adjustments and enhancements for specific applications:

• Security Access Control.
• Pet Tracking Systems.

Conclusion
This project exemplifies the integration of different technologies, such as GPS and IoT, to create a simple yet effective Dog Band system. The combination of hardware components and software tools offers pet owners a valuable tool for monitoring and ensuring the well-being of their dogs.
