    Smart Building (Prototype Alat)

    Current technological developments increasingly facilitate the conduct of human activities. But also adds many new problems such as high rise buildings that have a lot of ground, making it difficult to monitor the existing space in the building. To facilitate such work, then designed a tool for controlling and monitoring electric appliance in the office/building. This tool basically consists of two electrical devices are controlled via rs485. In the monitoring system consists of several electronic circuits which function light sensor for monitoring lamp, a voltage sensor function is to monitor the voltage-controlled, microcontroller (Arduino) serves as a data processing unit, in order to control and monitor the data is then sent to a computer for display to the application acquisition of data via RS-485 as a communication of some of the microcontroller to the computer. While the control system consists of an electric circuit breaker in which there is a relay and relay driver circuit, this circuit AC current will decide when it gets a signal or data from a computer and processed by a microcontroller. In making this tool a voltage source, a light sensor, voltage transformers, communication RS-485 and ADC on the microcontroller is important to note because it will affect the accuracy in reading the voltage condition, lights, and RS-485 communications. For feedback from the controlled device used a light sensor and voltage sensor. Sensor voltage is used to detect the voltage on the device being controlled, while the light sensor is used as a detector lights. To find out the control data input from the user database is used as a control data storage media.
