Abstract

The design of the detection system in this study using ESP32 module that includes Wi-Fi: 802.11 b / g / n and Bluetooth: v4.2 BR / EDR and Bluetooth Low Energy (BLE). In general, the automatic door lock system using a fingerprint or RFID card in its implementation, but this study using BLE which is a component of iBeacon which has a function as a result of the fingerprint and RFID card. ESP32 have a duty to control the door lock in order to open and lock the door using relays and solenoid system, in addition to the BLE on ESP32 serves to detect the presence of individuals where Bluetooth Device Address (BD_ADDR) smartwatch or individual gadget is already registered on ESP32. Based on the experimental results, the system can detect a user's presence smartwatch on the Received Signal Strength Indicator (RSSI), which is determined on the program was uploaded to ESP32. This system can also be developed in the future and applied to a variety of special purposes such as absenteeism, indoor mapping, and smart home.

Abstract

Wireless sensor network is a common method used in the design of shared resource interconnection infrastructure at a location point to provide optimal performance. The main factor in the design of a wireless sensor network (WSN) communication protocol in the form of coordination optimization efforts between nodes, one of the effective methods that can be made to achieve such conditions is the provision of nodes using the publish / subscribe messaging system protocol. This research discusses the implementation of publish / subscribe messaging system protocol on wireless building network system based on NRF2L01. Discussions include simulation, design, implementation, application testing and system performance both on a work-to-work and performance-by-node performance. The results showed the system was able to monitor all information and control equipment from a building through a web interface making it easier for officers to maintain and supervise a building, then to test the performance of nodes with a fixed data packet size of 32 bytes, the delay value for each node is less than 1 second, then for the minimum throughput 250 kbps data rate obtained at 5.9 Kbps and the maximum throughput obtained at 72 Kbps and for packet loss of at least 0.59% while the maximum packet loss of 13.23% and the standard deviation value of delay, throughput and packet loss are smaller than the average value, the data is not very varied (stable).
