Energy saving home alert system / Afiq Suhail Sazali

Home break-ins have been happening a lot since the old times especially during nighttime as there are fewer witnesses during the night or the homeowner is asleep, so the chances for robber of getting caught is low. In order to prevent the home break-ins, home alert systems have been around for a while with the purpose of ensuring the safety and security around the house. However, some of the home alert systems is using the outdated technologies which some of them are complicated, a bit expensive and require high energy consumption that eventually leads to high electricity bills. For this reason, the main objective of Energy Saving Home Alert System is to develop an energy-efficient home alert system that uses minimal energy consumption so it can reduce electricity bills for the user. Another objective of Energy Saving Home Alert System is to successfully connect it with the Internet of Things (IoT) using a microcontroller with integrated Wi-Fi, ESP32 so the user can receive a notification on their phone. The component that The Energy Saving Home Alert System will be use are Light Dependent Resistor (LDR) sensor, Passive Infrared (PIR) sensor, and IR Adjustable Proximity Sensor as an input and the output of this project are lamp, buzzer, and LED. This project will be automatically operating during nighttime due to the usage of Light Dependent Resistor (LDR) sensor and Passive Infrared (PIR) sensor to reduce the usage of energy consumption of lamp and the project itself. The programme for this project is being done and execute using Arduino Development Environment (IDE). However, for the Internet of Things (IoT), it uses Blynk to connect the microcontroller and the user smartphone via Wi-Fi.
