Monitoring Location Prototype Using Lora Module

Abstract

The number of child abduction cases in Indonesia today is always increasing every year, this has given concern to parents in leaving their children to play outside the home. Therefore, a device that can detect the presence of children when outside the home was needded. At this time, some devices can monitor ones location easily and quickly, such as Smartwatch and GPS Tracker, but the device must be connected to the internet With these conditions, it needs a device that can transmit information in real time without any dependence LoRa module are using low frequency radio as data transmission medium, can be built a Location monitoring prototype without connecting to internet network. From the examination results, the built system successfully shows the real time location coordinate point with a maximum data transmission limit of 2 KM for Line Of Sight (LOS).

Air pollution monitoring system using LoRa modul as transceiver system

“…And the system can not read the TELKOMNIKA ISSN: 1693-6930  Air pollution monitoring system using LoRa modul as transceiver system (Mia Rosmiati) 591 information the receiver transmits for the maximum distance of transmitter and receiver at a distance of 1.7 Km. The maximum distance of using LoRa/GPS HAT with the LOS scenario is 2 KM [26]. Furthermore the fastest data delivery time Range is at a distance of 1.3 KM variation of testing with the acceptance of the data with GPS coordinates and it only took about 1-3 seconds.…”
