Abstract

This paper discusses the security system of lift devices and rooms that  integrated with one Radio Frequency Identification (RFID) device. The RFID tags are small, wireless devices that help identify objects that  can provide convenience, security and convenience for users  to improve service quality base on on the Arduino Mega 2560 microcontroller. The results of control integrated system design of between elevator doors with private rooms and other facilities can be done well. In this design, the visitor management system becomes the central integrated security system because only visitors who have access can utilize various facilities in accordance with the existing code in RFID, so this result is very potential to be applied for various control vital objects for more secure system security.

Abstract

Instruments gamma radiation monitoring system was successfully developed. The instrument can measure the value of radiation exposure in an environment or material. The system was designed using sensor instrumentation Geiger tube M4011 and NGMC Module V1 using a web data base server. Sensor Geiger tube M4011 used had detection capabilities between 0mR / h ~ 120mR / h γRay. Data v alues gamma radiation that has been detected by the sensor is processed by the Geiger tube M4011 Microcontroller Atmega 328. Microcontroller 328 then sends the data that has been read into the webbased database serverusing Internet network GSM. In this system use web interface that allows users to monitor gamma value, without requiring a special receiving station. Basedon the results of validation of the value of gammaray radiation from the Geiger Counter, by means of Geiger Muller standard, Geiger counters and Geiger Muller has value misprint in a row in the lab ecology (4:06 ± 0:21) and (4:08 ± 0.20), at a distance of 4 cm material cesium 137 (9:20 ± 0.20) and (10.2 ± 0:28), and the material cobalt 60 (22:36 ± 0.40) and (22:04 ± 0.36), at a distance of 8 cm material cesium 137 (5.94 ± 0.20) and (5.78 ± 0.21), and materials cobalt 60 (15.96 ± 0.40) and (16:04 ± 12:23), at a distance of 12 cm material cesium 137 (4.76 ± 0:13) and (4:52 ± 0:16), and the material cobalt 60 (11.72 ± 0.21) and (12:46 ± 12:22).
