Infant Incubator Project

Overview

This project involves the creation of a model infant incubator that provides real-time monitoring of temperature, humidity, and heart rate. The system is equipped with alarms for under-temperature conditions and procedures to reset the temperature to the desired level. Additionally, a color sensor is included to detect symptoms of jaundice in infants.

Materials Used

1. Arduino Board

   • Acts as the central controller, managing the various sensors and actuators.

2. DHT Sensor (DHT11 )

   • Measures the temperature and humidity within the incubator.

3. Pulse Sensor

   • Monitors the infant's heart rate.

4. Color Sensor (TCS3200 or TCS2300)

   • Detects jaundice symptoms by analyzing the skin color of the infant. Triggers an alarm if severe jaundice is detected.

5. Liquid Crystal Display (LCD)

   • Displays temperature, humidity, and heart rate readings.

6. Relay Module

   • Controls a heating element (e.g., a yellow heat lamp) to adjust the temperature if it falls below the desired level.

Features

• Real-time Monitoring:
  • Continuously measures and displays temperature, humidity, and heart rate.
• Temperature Control:
  • Automatically activates a heating element if the temperature drops below a preset threshold.
  • Deactivates the heating element once the temperature returns to the desired level.
• Jaundice Detection:
  • Uses a color sensor to detect symptoms of jaundice and triggers an alarm if necessary.
• Alarms:
  • Alerts users in case of under-temperature or severe jaundice.

Setup and Installation

1. Hardware Setup:

   • Connect the DHT sensor to the Arduino for temperature and humidity readings.
   • Attach the pulse sensor to the Arduino for heart rate monitoring.
   • Mount the color sensor inside the incubator and connect it to the Arduino.
   • Connect the LCD to the Arduino for displaying sensor readings.
   • Set up the relay module to control the heating element.

2. Software Setup:

   • Install the Arduino IDE on your computer.
   • Install necessary libraries for the sensors (e.g., DHT, PulseSensorPlayground, TCS3200).
   • Upload the provided Arduino sketch to the Arduino board.

Usage Instructions

1. Power On:
   • Ensure the Arduino and all connected components are properly powered.
2. Monitor Readings:
   • Observe the temperature, humidity, and heart rate on the LCD display.
3. Respond to Alarms:
   • If an alarm sounds due to under-temperature or jaundice detection, take appropriate action as guided by the system.
4. Adjust Settings:
   • Modify the TEMPERATURE_THRESHOLD in the Arduino sketch as needed to suit specific requirements.

Troubleshooting

• No Readings on LCD:
  • Check all connections and ensure the LCD is properly initialized in the code.
• Sensors Not Working:
  • Verify the correct pins and libraries are used in the Arduino sketch.
• Heating Element Not Activating:
  • Ensure the relay module is connected and functioning correctly.
