Pin Configuration

Heart Rate Pulse Sensor Module Documentation
Pin Description:
The Heart Rate Pulse Sensor Module has a total of 4 pins, each serving a specific purpose. Below is a detailed explanation of each pin:
1. VCC Pin:
Function: Power supply pin
Description: This pin provides power to the module and is typically connected to a voltage source ranging from 3.3V to 5V.
Connection: Connect VCC pin to a power source (e.g., Arduino's 5V pin or a 3.3V regulator output).
2. GND Pin:
Function: Ground pin
Description: This pin provides a ground connection for the module and is used to complete the circuit.
Connection: Connect GND pin to a common ground point (e.g., Arduino's GND pin or a breadboard's ground rail).
3. OUT Pin:
Function: Analog output pin
Description: This pin provides an analog signal that represents the heart rate pulse reading. The signal is a varying voltage level that corresponds to the pulse amplitude.
Connection: Connect OUT pin to an analog-to-digital converter (ADC) input on a microcontroller (e.g., Arduino's A0-A5 pins) to read the pulse signal.
4. VIN Pin:
Function: Optional power pin (not recommended for use)
Description: This pin is not recommended for use, as it is intended for internal module circuitry. Connecting a power source to this pin may damage the module.
Connection: Do not connect anything to this pin.
Connecting the Pins:
To connect the Heart Rate Pulse Sensor Module to a microcontroller (e.g., Arduino), follow this structure:
Connect VCC pin to a power source (e.g., Arduino's 5V pin).
Connect GND pin to a common ground point (e.g., Arduino's GND pin).
Connect OUT pin to an ADC input on the microcontroller (e.g., Arduino's A0-A5 pins).
Example Connection Diagram:
Here's an example connection diagram using an Arduino Uno:
VCC (Heart Rate Pulse Sensor Module) 5V (Arduino Uno)
GND (Heart Rate Pulse Sensor Module) GND (Arduino Uno)
OUT (Heart Rate Pulse Sensor Module) A0 (Arduino Uno)
Remember to use a breadboard and jumper wires to connect the module to your microcontroller. Always double-check your connections to ensure correct and safe operation.

 Communication Protocol: Analog Output (0-5V)
 Sampling Rate: Up to 100 Hz
 Accuracy: 2 BPM
 Power Consumption: <10mA

Hardware Connections

The Heart Rate Pulse Sensor Module has three pins:

VCC: Power supply (3.3V - 5V)
 GND: Ground
 OUT: Analog output signal (0-5V)

Software Examples

The following examples demonstrate how to use the Heart Rate Pulse Sensor Module in different contexts:

Example 1: Arduino Integration

In this example, we will connect the Heart Rate Pulse Sensor Module to an Arduino board to read and display the heart rate data.

```cpp
const int pulsePin = A0; // Connect OUT pin to Analog Input A0

void setup() {
  Serial.begin(9600);
}

void loop() {
  int pulseValue = analogRead(pulsePin);
  int heartRate = map(pulseValue, 0, 1023, 0, 200); // Convert analog value to heart rate (BPM)
  Serial.print("Heart Rate: ");
  Serial.print(heartRate);
  Serial.println(" BPM");
  delay(1000);
}
```

Example 2: Raspberry Pi (Python) Integration

In this example, we will connect the Heart Rate Pulse Sensor Module to a Raspberry Pi board using an ADC (Analog-to-Digital Converter) module to read the analog output signal.

```python
import time
import adc1Lib

# Set up ADC channel
adc_channel = 0
adc = adc1Lib.ADC1(adc_channel)

while True:
    pulse_value = adc.read_adc()
    heart_rate = (pulse_value / 1023)  200 # Convert analog value to heart rate (BPM)
    print("Heart Rate: {:.2f} BPM".format(heart_rate))
    time.sleep(1)
```

Example 3: MicroPython (ESP32/ESP8266) Integration

In this example, we will connect the Heart Rate Pulse Sensor Module to an ESP32/ESP8266 board running MicroPython.

```python
import machine
import time

# Set up ADC pin
pulse_pin = machine.ADC(machine.Pin(32)) # Connect OUT pin to ADC Pin 32

while True:
    pulse_value = pulse_pin.read_u16()
    heart_rate = (pulse_value / 65536)  200 # Convert analog value to heart rate (BPM)
    print("Heart Rate: {:.2f} BPM".format(heart_rate))
    time.sleep(1)
```

These examples demonstrate how to use the Heart Rate Pulse Sensor Module to measure heart rate data in various IoT applications.
