Abstract:
The main objective of this project is to develop a home security system using an Arduino board with
sensor controlled by LCD. As technology is advancing so houses are also getting smarter. Modern
houses are gradually shifting from conventional switches to centralized control system, involving
remote controlled switches. Presently, conventional wall switches located in different parts of the
house makes it difficult for the user to go near them to operate. Even more it becomes more difficult
for the elderly or physically handicapped people to do so. Remote controlled home security system
provides a most modern solution with sensor. In order to achieve this, a sensor module is interfaced to
the Arduino board at the receiver end while on the transmitter end, a Arduino application on the
display sends ON/OFF commands to the receiver where loads are connected. By touching the
specified location on the sensor, the loads can be turned ON/OFF automatically through this
technology.
By this security system we can detect gas, fire, thief detector and automatic road lamp ON/OFF
system.
We can use gas detector in kitchen, car garage and all gas component in the industry, home etc.
By the temperature sensor we can detect fire and get fire alarm by the buzzer and emergency signal
light. We get notification by using LCD display.
We can detected thief by using motion detector sensor. We can use it in the home, garage and
industry. When we absence this place the sensor detect thief.
By using LDR we can solution the light on/off system automatically in day time and night time. We
can use the LDR on Road lamp, car parking area.
