Abstract :

The Increasing Demand For Intelligent, Autonomous, And Remotely Accessible Surveillance Systems Has Led To The Development Of Multi-functional Robotic Platforms Using Internet Of Things (IoT) Technologies. This Project Presents The Design And Implementation Of An IoT- Based Smart Multi-Application Surveillance Robot Capable Of Performing Real-time Monitoring, Hazard Detection, And Remote Control Through A Wireless Network. The Proposed System Is Built Around An ESP32 Microcontroller, Which Acts As The Central Processing And Communication Unit, Integrating Sensing, Actuation, And IoT Connectivity. The Robot Is Equipped With Multiple Sensors, Including A Gas Sensor For Detecting Hazardous Gas Leaks, A Flame Sensor For Fire Detection, A Doppler Sensor For Motion And Intrusion Sensing, And A Metal Sensor For Identifying Metallic Objects, Making It Suitable For Defense, Industrial, And Security Applications. A Night Vision Camera Enables Visual Surveillance In Low-light And Nighttime Environments. Sensor Data Are Continuously Processed By The ESP32 And Displayed Locally On A 16×2 LCD, While Critical Alerts Are Communicated Remotely Using The Blynk IoT Platform Over Wi-Fi. Mobility Is Achieved Using DC Motors Controlled Through A Motor Driver, Allowing Precise Movement Of The Robot S Left And Right Wheels. In Emergency Or Abnormal Conditions, An Onboard Buzzer Provides Immediate Audible Alerts. The System Is Powered By A Battery Supply, Ensuring Portability And Uninterrupted Operation. Overall, The Proposed Surveillance Robot Offers A Low-cost, Scalable, And Versatile Solution For Smart Monitoring In Military Zones, Disaster-prone Areas, Industrial Sites, And Restricted Environments, Enhancing Safety Through Real-time Sensing And IoT-enabled Remote Supervision Keywords— IoT, Surveillance Robot, ESP32, Smart Monitoring, Multi-Application System, Gas Sensor, Flame Sensor, Doppler Motion Sensor, Metal Detector, Night Vision Camera, Blynk IoT, Remote Monitoring Etc.,
