Abstract: Some existing security systems are easily tripped by small critters such as cats or squirrels and react to slightest movement. These factors trigger annoying false alarm and even worse, some alarms are unable to alert house occupants of unexpected intrusion and goes off when it is too late. These alarms also, cannot be reset unless the owner is in the house to push the reset button. The objective of this project is to design a system that senses changing pressure on different spots which are the roof and ceiling as well as to construct a system that warns and notify the owner and the house occupants. This project is developed by using Arduino Mega aided with Node MCU to enable internet implementation that can reset the system through button widgets. Inputs used are Piezoelectric Sensor and Passive Infrared (PIR) Motion Sensor while the outputs are Light Emitting Diode (LED), Liquid Crystal Display (LCD) and buzzer. Hence, this project will develop a system that can prevent false alarm and alert household of unexpected intruders as well as notify the owner of the house of their property while they are on a vacation or outstation for work.
