These changes are converted into electrical signals, which the Arduino reads to calculate the BPM. Project Setup: Pulse Sensor Connection: The Pulse Sensor has three pins—VCC (power), GND (ground), ...

The software constists of two components. First, an Arduino sketch to process the raw sensor values and to detect a revolution of the ferraris disc, and second a daemon which receives the energy ...

Because of this, a system to measure pulse rate has been devised in this work. Pulse detection is a straightforward but crucial aspect of keeping track of a patient’s health. The hardware used in this ...

The working of HC-SR04 is simple. When the sensor is triggered (a short 10µs pulse to the trigger input pin 2 from Arduino Uno board), the transmitter sends a high-frequency sound signal at 40kHz. The ...

Li-Fi Receiver Section using Arduino. In the receiver section, the LDR sensor receives the visible light pulses from the transmitter side and converts it into interpretable electrical pulses, which is ...

In addition to monitoring blood pressure, cholesterol levels, lifestyle habits, and medical history, heart rate also serves as an essential measure in assessing overall health. The heart rate is a ...
