Health Monitoring System

This project is an IoT-based health monitoring system that measures heart rate and temperature using a Pulse Sensor and an analog temperature sensor. The system displays real-time data on an LCD screen and sends the information to ThingSpeak for remote monitoring.

Features

• Real-time heart rate monitoring using a Pulse Sensor.
• Temperature measurement in Fahrenheit using an analog temperature sensor.
• LCD display showing heart rate (BPM) and temperature.
• Sends data to ThingSpeak for remote monitoring via ESP8266 Wi-Fi module.
• Visual and auditory indicators for heartbeats.

Hardware Required

• Arduino board (e.g., Arduino Uno)
• Pulse Sensor
• Analog temperature sensor
• 16x2 LCD
• ESP8266 Wi-Fi module
• Resistors (if necessary)
• Breadboard and jumper wires

Circuit Diagram

Hardware Setup

1. Connect the Pulse Sensor purple wire to analog pin A0.
2. Connect the temperature sensor to analog pin A1.
3. Connect the LCD pins as follows:
   • RS -> Pin 12
   • EN -> Pin 11
   • D4 -> Pin 5
   • D5 -> Pin 4
   • D6 -> Pin 3
   • D7 -> Pin 2
4. Connect the ESP8266 module (TX, RX) to pins 9 and 10 respectively.
5. Connect the power and ground pins accordingly.

Result Display

Upon running the system, the LCD displays real-time heart rate and temperature readings. Additionally, the data is sent to ThingSpeak for monitoring.

ThingSpeak Output

Usage

1. Upload the code to your Arduino board.
2. Connect the hardware as described in the setup.
3. Open the Serial Monitor to view real-time heart rate and temperature readings.
4. Monitor the data on ThingSpeak for remote access.
