A Building Management System (BMS) is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems.   The main aim of the project is to design an Arduino based smart building management system that can monitors and controls the building’s electrical equipment such as power system, fire systems and water level in tank. This project makes a use of ultrasonic sensor to measure the water level in overhead tank. Fire sensor is uses to detect the fire and POT is uses to vary the voltage of the bulb.   The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.   The intelligent device which is capable of performing the task is Arduino. SR04 sensor, Fire sensor, AC water motor along with relay, AC bulb along with relay and Buzzer is interfaced to the Arduino microcontroller. Arduino microcontroller continuously read the data from SR04 sensors and based on water level Arduino can control the water motor through relay. Here we are using relay works as a switch to on-off the water motor. If the system detects fire, it can turn ON the buzzer for fire alert. In real-time power fluctuations are occurred automatically but, in this project, we create a high/low voltage using POT. The status of the project will display on LCD. To perform this intelligent task is ARDUINO using embedded C programming system.
