Abstract

Temperature is a part of the natural condition that  related to human activities. Many human activity is affected by temperature fluctuation factors. For example, in this case is a temperature monitoring at these broiler farms and database monitoring center computer. Room temperature for  places are two examples of the human activities that the temperature factor is concerned. Until now, time temperature monitoring activity is done manually, thus it is need a monitoring tool that can be viewed from  the computer interface.To save time and cost, application for temperature monitoring equipment is made so that the results can be seen from a distance. The applications are user friendly, so users can easily find out the temperature value.Application for temperature monitoring equipment is useful to support the activities of monitoring the temperature. From the experimental results, the application for temperature monitoring equipment that uses radio frequency results can be viewed from a computer interface, so as to streamline the performance of temperature monitoring.

Abstract

Digital image was needed us a medium of information that can be transmitted by cable or wireless media. To obtain digital images must use a tool such as a camera. Users can use the camera to get a digital image with the remote sensing method on an object in a particular place. In the daily activities, users can take advantages of the digital image (pictures or video) that are useful for media documentation, monitoring system in somewhere and others. The design of this tool using LS_Y201camera to capture a digital image and wireless as a data transmission media. In this case a wireless media use Ultra High Frequency transmitter and receiver that support for remote sensing. Users run the tool through an application that is connected with a wireless media. This application is designed byDelphi7. Applications and wireless camera was made for simulation media of remote sensing and monitoring system in the blank spot area. The test result of applications and tools that use the Ultra High Frequency (wireless), can be viewed from a computer interface. In this case, the signal strength ofthe transmitter greatly affect the maximum distance that can be taken to make capture process. The test results are as follows: the best results at a distance of 10 meters = 011110102 (12210); distance of 20 meters = 011100112 (11510); distance of 30 meters = 011110102 (12210); distance of 40 meters =011011112 (11110); distance of 50 meters = 011100102 (11410). So the best distance to digital images transmission through a wireless networks are at a distance of 40 meters.

Abstract

Digital image processing of a system capable of generating digital image data and software as a medium to display the digital image data that uses radio waves to send data in HEX and convert in the form of images. Linksprite camera which enable to produce the digital image data and utilize the arduino UNO as a controller to send commands to the camera image capture and send the digital image data to the PC. The process of digital image based data transmission by radio waves utilizing the XBee Pro Series 1 . Results of testing the system implemented in the outdoor can take a longer distance when compared with the application of the system in the room . At a distance of 10-250 meters complete the full HEX data transmission and produces good images , with time ranging 2m.29s.39ms-2m.36s.56ms. Distance of 260-450 meters with a time of 2m.05s.02ms - 06ms 2m 01s but the picture quality is not good. At a distance of 500-530 meters with a time of 1m.10s.23ms-0m.50s.59ms produce images that are very less. While the distance of > 550 meters is the limit HEX data transmission capability to the receiver. The ability of the system mileage in the process of data transfer shorter if applied indoors. Distance of 1-60 meters with a time of 2m.29s.39ms - 60ms.2m.34s produce good quality images. At a distance of 80 meters with a time of 1m.25s.59ms produce poor images, and with a distance of 90 meters with a time 0m.35s.49ms produce images that are very less . While the distance of > 100 system not able to perform HEX data transmission

Abstract

The geographical position of Indonesia is located in an earthquake-prone area that is potentially most earthquake-tsunami, it takes a transmission medium to connect the cameramonitoring results between the sender and receiver of information or data that may provide information to the natural disasters. The transmission media can be a media streaming seawater and alarm monitoring that is connected with vibration sensor that functions as a medium for early warning of natural disasters. From the test results it can be concluded that the alarm system warning of earthquakes, able to work well as vibration sensor detects vibration. As well as video streaming process can run well on a LAN network using HTTP protocol 8080. Society as a client can access the video streaming server via the address specified by the application server.
