Abstract
The Air-conditioner controller consists of two significant parts, Being the hardware and software. The hardware is three main parts: a motion sensor circuit, the air-conditioner controller circuits, and main control board with internet interface. The software program is written in C language on-board ET-PIC16/32 START KIT for controlling the air-conditioner either by the control panel or via the internet using HTML and JavaScript for control and display of results. The result of data has a record in the database. For the testing of the air-conditioning controller included switching on and off, setting temperature, adjusting the fan level and setting the operating time via the control panel and web-page. The result was that it functioned as specified and intended, and the temperature measured by the sensor showed an average deviation of ±1.47 degree C and average margin of error 5.99 percent.
