The system includes a PIR sensor to detect human motion, a metal sensor to identify the presence of metallic objects, and an ultrasonic sensor to monitor distance or detect unauthorized object placement. When a metallic object is detected by the metal sensor, the servo motor is automatically triggered to open—simulating access control mechanisms such as opening a security gate or container for further inspection. Simultaneously, a Buzzer is activated to provide an audible alert, and a GSM module sends an instant SMS notification to airport security personnel. Whenever human movement is detected or an object is found within the restricted range, the system immediately activates security actions.

A GSM module is used to send an instant SMS alert to a predefined mobile number, informing security personnel about the detected activity. At the same time, a Wi-Fi module uploads real-time sensor data to a web server or cloud platform, allowing live monitoring of sensor status through a web display. The system provides continuous surveillance, quick alert generation, and remote monitoring for improved security and safety.

 Metal detection with automated servo motor activation.

 PIR sensor for motion detection.

We can control the robot using smart phone through iot required task like moving forward, reverse, turning left, turning right and stop.

This consists of a Microcontroller based control system, battery powered DC motors and Esp8266 WIFI Module.

The controlling device of the whole system is a Microcontroller. Wi-Fi module, DC motor along with driver, buzzer with driver is interfaced to the Microcontroller. The data received by the Wi-Fi module from Android smart phone is fed as input to the controller. The controller acts accordingly on the robot movement,  this is fed as input to the microcontroller then the microcontroller give the alert through buzzer. In achieving the task the controller is loaded with a program written using Embedded ‘C’ language.

Soldiers are very important people who always strive for the security of the country. They are supposed to work at extreme temperatures (very high or very low temperatures). This will lead to health damage. So, a E- uniform is designed to avoid adverse effects caused due to temperature changes.

The controlling device of the project is PIC microcontroller. Metal sensor, GSM, GPS, panic switch,peltier plate,buzzer and Relays along with peltier plate and cooling fan are interfaced to PIC microcontroller. Microcontroller will switch on the peltier plate to provide the hot/cool to the soldier at inside of the jacket.When the person presses the panic switch, microcontroller will take the location from GPS module and sending this location to the predefine mobile number through GSM modem in the form oflatitude and longitude values and upload the data into the thingspeak cloud through ESP8266 WI-FI module.The status of the project will display on LCD module.This uniform consist of contains metal detector, if the sensor detects metal this data process to the microcontroller, then microcontroller will activate the buzzer for alerts.All this equipment is placed in soldier jacket and solar panel on the soldiers cap.solar energy is obtained stored into the battery through charging circuit.
