Home automation is the automatic control of electronic devices of the home. This system is used to monitor and control the home electronic appliance. Arduino home automation is a network of electronic gadgets and communication medium which are integrated via the internet. As we all know nobody can imagine his life without these electronic devices and our schedule is busy we want everything in our control. For this, we need the latest technology electronic component to build a smart home. This system consists of Electronic components such as Arduino Programming and hardware, working of PIR sensor, relay module, some wire, and lamp. Everybody has demanded more and more functionality according to their needs. No doubt, every year, these components are coming with better features and specifications .As they are enhanced with the latest technology software and hardware. There are several advantages of home automation using Arduino and PIR sensors because after integration of them we can control and monitor remotely all home devices. ArduinoAn Arduino describes as an open-source electronics Platform used as hardware and software both it is a microcontroller-based which is easy to use for programming and hardware section. Many Arduino circuits consist of an Atmel 8-bit AVR microcontroller. Arduino hardware is capable to read input signals coming from the sensor, finger, switch or button and turn its output like a fan, relay, motor, light or LED according to the coding of the user. Arduino programming coding is written in C++ and with some special functions. After coding it is processed and compiled to machine language. Arduino can interact with buttons, motors, speakers, smartphones or TV, GPS units, cameras, and the internet. PIR sensorA PIR sensor is an electronic sensor that is used to detect the object measuring infrared light radiating from the objects. It works on the Principle of passive Infrared radiation emitted by objects nearby. It is capable to sense the motion of the object. PIR sensor and Arduino hardware or software interface are compatible. PIR sensors are also compatible with Raspberry pi. They are used in Many Electronics Projects as they are easy to use, small, and inexpensive. Working of Home automation circuitThis system is Depends on the detection of Infrared rays which are used to turn on the latest Electronic Gadgets when somebody enters the room automatically according to user coding. This is done Because the PIR sensor detects the heat rays emitted by any living being (human being). After detecting the object it gives an input signal to Arduino Circuit. Then Arduino Processes the code and compiles it in machine language act according to the command given by the user to the all connected home appliance. The Gadget stays on as long as the person is in the room. Advantages of Home Automation1. Money Saving 2. Controlling and monitoring remotely 3. Safety and security 4. Convenience and comfort 5. Energy Saving and management Summing –up wordsHome Automation using Arduino and PIR sensor implemented in many application according to the need of human being. Arduino home automation growing as demands increased in various domestic applications such as lighting, safety and security, energy management, and entertainment. Due to many advantages Automation is growing speedy in every firm for example office, transportation systems, retail, hospitals, enterprises, and factories.
