Connect the USB cable to the power bank to ensure a stable power source for the Wearable heart rate monitor device. Attach the ECG electrodes to the ECG module. Place the green module near the right ankle and position the yellow electrode on the left arm, while the red electrode goes on the right arm. This specific electrode placement enables accurate measurement and signals acquisition from the heart. Once the setup is complete, observe the ECG heart rate monitor device. If a blinking red light appears, the device is properly connected to the power bank via the USB cable and receiving power. The ECG receiver sensor node is responsible for detecting the ECG signal. The sensor node has an LED that changes colours based on the values received from the ECG. This LED serves as a visual indicator to interpret the ECG results.

 During ECG monitoring, the LED colours convey important information. Typically, a green LED indicates normal ECG values, representing a healthy heart rate. If the LED changes to blue, it suggests moderate values, indicating a deviation from the normal heart rate. On the other hand, if the LED turns red, it signifies higher values, suggesting a potentially alarming heart rate. These colour changes help easily identify and assess the ECG values in real-time.

 By following this methodology of accurately setting up the ECG heart rate monitor system, including proper power connection, correct electrode placement, monitoring the power supply with the blinking red light, and interpreting ECG values using LED colours changes, one can effectively monitor the heart's electrical activity and identify any deviations from the normal heart rate.
