A User-Friendly Low-Cost Mobile App Based Home Appliance Control And Circuit Breaker

Along with the constant improvement of different electronic devices, the safety of technicians has also become a matter of great concern, as the lives of technicians are at risk while they work by switching off the circuit breakers, because even after the circuit breaker has been turned off, someone can unknowingly turn it on while the technician is still working. There must be a system for ensuring security for the technicians. Also, people do not like having to walk to switches all the time to turn on/off appliances such as fan/light/air conditioner. It results in wasted energy because of unnecessarily keeping appliance on. To solve these problems, we came up with a system with password controlled circuit breakers and wireless control of home appliances using an Android app. It replaces the traditional circuit breaker on/off system with a password controlled system, where nobody can turn on the circuit breaker without the password. Remote control of the home appliances helps the user save electricity. It also enhances the quality and comfort of life. The system also includes a home security mechanism against illegal intrusion using a password controlled door lock system and a mechanism for detecting dangerous gas leakages. The system is built using an Arduino mega microcontroller, a Bluetooth module, a matrix 4x4 keyboard, a methane gas sensor and an Android mobile application. The whole system can be made compact in an integrated system.
