Abstract


The use of LDR sensor resistance values for the purposes of engineering in particular as anti-theft sensor on the circuit, sutter cameras, alarm. Dust Detector tool uses Microcontroller AT89S51 sebagau control system and sensor LDR as sensor pendteksi thickness of dust scattered in the environment. Testing and analysis tools do in part -part LDR sensor system such as testing, testing power supply, LCD testing, and testing of the entire tool. By the time the dust is read by the sensor, then the result of great content will be displayed by the LCD screen. If the dust hazard is detected, then the buzzer will give a warning alarm

Keywords: Microcontroller, LDR, LCD, DUST
