Abstract

The development of electronic technology especially with regard to automatic control is increasing in line with the development of the science and the automation of this automatic control technology is applied to the different electronic devices used daily to further assist in human work, However many things the current remote control system still has a shortage of people having to use a cost report. such as a pulse or a packaged Internet data currently used using a gateway text or the Internet. For the time being, automatic designs in remote control systems that use modulation frequencies work on radio frequencies, 4.333 MHZ. Which enables it to turn on and off electronics that are commonly used in everyday life. Examples: fans, water pumps, and lights. This device activates the bluetooth using a smartphone which a frequency of hc-12 will read then be processed and received by arduino. With this deleted design, the prototype of the remote control system, made possible by artificial androids to shut down and activate the home smart electronic devices.

Abstract

The current development of control and automatic system technology allows operators to easily turn on and off electronic devices remotely without having to make direct contact, this is very effective in saving time and helping one's work become easier. Currently electrical energy is a basic human need. However, the use of electrical energy is not used optimally, its use tends to be excessive, the cause is due to someone's negligence of an electrical device that forgot to turn it off. To overcome this problem, it is necessary to have an automatic control system that can control the switch to help minimize the waste of electrical energy. However, various kinds of automatic control system devices have drawbacks, including requiring an internet connection or using an SMS gateway so that they can be controlled remotely, which will increase spending on the budget for internet or credit needs every month. The method used in this design uses Arduino uno, HC – 12 module, ZMTC103C current sensor, and relay. This tool works when an instruction signal is received via the HC-12 module then the signal is forwarded to Arduino to turn on or turn off the electric device through a relay, the current sensor detects the condition of the electric device. From the results of testing the control system successfully turns on and off loads in the form of lights, fans, water pumps properly and can detect lights that go out.
