This security system aims at improving the security in hostel rooms.
To equip the rooms with a cheap but a fairly reliable systems we would use ultrasonic sensors to detect movement when an individual is not in his/her room.
The setup consists of a simple circuit wherein ultrasonic sensors are placed at various heights at a room entrance. It is then linked to an alerting system which is monitored by the logic as provided in the microcontroller.The interface for this will be a web page generated by a web server.Those with a link to the page can access the system.Trusted individuals such as friends and hostel guard will be notified of any intrusions.
Now to further enhance this system so as to ensure locking of rooms and to facilitate automated unlocking using handheld devices a servo motor can be attached to the latch of the door and then can initiate auto locking and unlocking process.
It can also be applied to cupboards/cabinets within the room.In case of an intrusion, the door will automatically be closed, after movement is detected.
This type of system is very cheap and affordable and also ensures that the components if damaged can be easily replaced. Moreover scalability can also be achieved at a low cost as multiple ultrasonic sensors can be connected to a single micro controller thereby drastically reducing costs.
This project uses Texas Instruments micro controllers like the MSP430 and the CC3200 and also uses requires Energia to code and work on these platforms
Some of the important hardware components required in this project are:
● MSP430 board
● CC3200 board
● Servo motor
● Ultrasonic sensors
● Jumper wires
● 2 power sources
Constructing the prototype
Create a web server using the CC3200 to host the information of the ultrasonic sensor and to detect any intrusion. To do this please do follow the code as provided
Use a MSP430 board to detect motion using an ultrasonic sensor. Now use the code as provided and make the circuit connections as shown so as to relay the information from the ultrasonic sensors to the web server
Use the MSP430 board so as to create an appropriate locking mechanism using servo motor and use the code provided to achieve the same
