Abstract: Agricultural land fire is a routine problem happened in Indonesia. A monitoring system to prevent the fire had been build utilised sensors and alarm activation. Sensors was used to detect the increase of temperature and vibration around plants. This procedure could activated alarm if the scale of measurement above the threshold numbers. Arduino microcontroller and Xbee moduls was functioning as transmitter and receiver between plants and user’s computer. Testing had been done and the systems researched properly as well as database output recorded the monitoring process.
