Arduino-based embedded automation system featuring real-time multi-sensor data acquisition, environmental monitoring, and threshold-based control of motors and alert devices.
The Embedded Multi-Sensor Monitoring and Control System is a real-time embedded automation project developed using Arduino Uno (ATmega328P).
The system continuously acquires data from multiple sensors and automatically controls various actuators based on predefined threshold values. It demonstrates practical implementation of embedded monitoring, sensor interfacing, data acquisition, decision-making logic, and automated control systems.
The project integrates:
- IR Sensor for object detection
- MQ-2 Gas Sensor for gas leakage monitoring
- LM35 Temperature Sensor for temperature monitoring
- HC-SR04 Ultrasonic Sensor for distance measurement
- DC Motor control using L293D Motor Driver
- Stepper Motor automation
- LED-based alert indication
All sensor readings and device statuses are displayed in real-time through the Serial Monitor.
Design and develop a microcontroller-based Data Acquisition and Control System capable of acquiring real-time data from multiple sensors and automatically controlling output devices according to predefined threshold conditions.
The system should continuously monitor environmental conditions, process sensor data, execute control actions, and provide real-time feedback to the user.

The IR sensor continuously detects the presence of nearby objects.
If an object is detected:
Object Detected
If no object is detected:
No Object Detected
The MQ-2 gas sensor continuously monitors the environment for gas leakage.
If gas leakage is detected:
GAS LEAKAGE DETECTED !!!
- LED blinks repeatedly as an emergency warning signal.
If no gas is detected:
No Gas Detected
- LED remains OFF.
The LM35 sensor continuously measures ambient temperature.
20°C
If Temperature ≥ 20°C
DC Motor ON
The DC motor is activated through the L293D motor driver.
If Temperature < 20°C
DC Motor OFF
The DC motor remains stopped.
The HC-SR04 sensor continuously measures object distance.
15 cm
If Distance < 15 cm
Object Close
- Stepper motor rotates clockwise.
- Stepper motor rotates anticlockwise.
If Distance ≥ 15 cm
Object Far
- Stepper motor remains stopped.
