Abstract

The Build up for the cow shed security system has been made with LDR (Light Dependent Resistor) censor with microcontroller AT89S51. This program can observe a cow shed security optimally. This system consist of hardware and software. Hardware consist of LDR (Light Dependent Resistor) censor, comparator (LM 339), microcontroller, relay and buzzer. In this system uses assembly language which implemented in microcontroller. In this system uses microcontroller AT89S51. This system will work according something which gate in the way LDR censor and will showed by Borland Delphi 7.0 in PC or Laptop. From this software making which has been done we had the result that this system can monitoring the cow of shed by LDR (Light Dependent Resistor) censor. Testing result shows that if someone try to enter the cow shed area, automatically LDR (Light Dependent Resistor) censor will detect and showed by software on PC or laptop. Beside that, we will hear the sound of buzzer (alarm) as early warning system.
