Home Automation with RTU Miniuno

This project is a home automation project that can easily view the status of the house inside. Each room is set up to detect fire, motion, or sound and raises an alarm upon the sensing data. The additional function is to send SMS using RTU MINIUNO. It also shows  view your house status via smartphone like following figures.

Parts

– 5 Relays
– 1 Buzzer
– PIR
– Arduino Ethernet Shield
– Arduino Uno

RTU can be applied as:
Digital output = control on / off lights, air conditioning, fans, garage doors, etc.
Digital Input = receive the output of PIR sensor (motion), fire sensors, sound sensors, an indication of the MCB trip and so on Other
Analog Input = measuring voltage, current, temperature, and other library sketch

The RTU can be monitored via PC or android phone. Software HMI via PC
