Connections are pretty simple and only a few wires. Connect the VCC and GND of the sensor to the 5V and GND pins of the Arduino. Then connect the output to the Arduino’s D2 pin. Here's how the ...

The temperature sensor is built using an NTC 10k thermistor, which changes its resistance in response to changes in temperature. The resistance of the thermistor is measured using the Arduino's analog ...

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), ...
