Smart NeoCare is an embedded control system for infant incubators designed to simulate the womb's environment for premature babies. Using Arduino, the system continuously monitors vital environmental parameters (Temperature, Humidity, Air Quality, Light) and automatically adjusts actuators to maintain stable conditions.
This project aims to reduce neonatal mortality by ensuring a safe, controlled, and responsive environment, minimizing the need for manual intervention by nursing staff.
- Temperature Regulation:
- Reads internal temperature via DHT11 and body temperature via Thermistor.
- Automatically activates the Heater if temp < 35°C and the Fan if temp > 35°C to prevent hypothermia or overheating.
- Air Quality Control:
- Monitors toxic gases using an MQ-2 Sensor.
- If gas levels exceed the safety threshold (>300), a Servo Motor automatically opens the ventilation window, and a Red Alarm LED triggers.
- Smart Lighting:
- Uses an LDR (Light Dependent Resistor) to detect ambient light.
- Automatically turns on internal lighting (White LED) when the room gets dark (<100) to allow visibility.
- Weight/Presence Monitoring:
- Utilizes an FSR (Force Sensitive Resistor) to monitor the infant's weight or presence on the mattress.
- Phototherapy Integration:
- Controls Blue LEDs for jaundice treatment functionality.
- User Interface:
- Displays real-time data (Temp, Humidity, Gas Level) on an LCD 16x2 screen for staff monitoring.
- Controller: Arduino Uno.
- Sensors: DHT11 (Temp/Hum), MQ-2 (Gas), LDR (Light), FSR (Force), NTC Thermistor (Body Temp).
- Actuators: Servo Motor (SG90), DC Fan, Heating Element (Simulated), LEDs.
- Display: LCD 16x2.
- Wiring: Connect sensors and actuators according to the pin definitions in
src/incubator_control.ino. - Libraries: Install the
DHTandLiquidCrystallibraries in Arduino IDE. - Upload: Flash the code to the Arduino board.
- Monitor: Parameters will be displayed on the LCD.
