Smart Pulse Monitoring Wristband with Health Alerts

Project Description:

We are seeking a skilled electronics engineer to design and develop a compact and user-friendly smart wristband that integrates a highly accurate pulse sensor with a small microcontroller. The wristband should also feature a rechargeable battery and a display for showing both battery percentage and heart rate (bpm).

Key Features:

1. Pulse Sensor:
- Utilize a high-precision pulse sensor for accurate heart rate monitoring.

2. Microcontroller:
- Integrate a small and efficient microcontroller to process and display real-time data.

3. Display:
- Include a clear and easy-to-read display to show heart rate (bpm) and battery percentage.

4. Rechargeable Battery:
- Design the wristband with a rechargeable battery for enhanced convenience and sustainability.

5. Health Alerts:
- Implement an alert system that vibrates and activates an alarm sound if the heart rate falls below 60 bpm or rises above 100 bpm.
- The alerts should continue until the heart rate returns to the normal range (60 to 100 bpm).

6. Compact Design:
- Ensure that the overall size of the wristband is comparable to that of a standard watch for comfortable and stylish wear.

7. Durable and Water-Resistant:
- Build the wristband with durable materials and consider making it water-resistant for everyday use.

8. Charging Port:
- Include a convenient and accessible charging port for recharging the battery.

Deliverables:
1. Schematic diagram of the circuit.
2. Printed Circuit Board (PCB) layout files.
3. Bill of Materials (BOM) specifying all required components.
4. Microcontroller code for data processing and control.
5. Design files for the wristband casing.
6. User manual for operation and troubleshooting.
7. Testing and calibration documentation.
