| ABSTRAK |
| Abstract This paper will discuss the benefits of piezoelectric vibration sensors with Microcontroller support brain and automatic controls. Applications of these sensors can be used or can be installed in places berbaya, early warning and can be controlled remotely. With this sensor humans can get information quickly, easily, accurately without having to approach the dangerous places. Hardware requirements of the design is a piezoelectric sensor, Microcontroller AT89C51, Op-Amp LM 393, A / D Converter, viewer, and Regulator 7805 and supported earth.asm Assembler language. Before testing the design implemented these tools, which are designed so that the system can run well and in accordance with their respective functions. To determine the performance of these sensors is the variety of different distances simulated vibrations with the same height. The simulation results show that the sensor can detect the vibration source to 200 cm from the vibration source graph distance vs. Value LCD display. With simulation results and analysis of the graph, the design of microcontroller-based piezoelectric sensors can be as additional knowledge and can be developed to meet the needs or solve problems much needed information.
