Abstract

Railway crossing gates are railway facilities or infrastructure to protect train travel and provide warnings to road users.  The  prototype  of  this  automatic  railway  crossing  gate  uses  an  Arduino  Nano,  LoRA RFM  95,  5  kg  Load Cell,  MG996R  Servo  Motor,  LED,  and  Buzzer.  In  component  testing  there  are  Load  Cell,  LoRa  RFM  95,  and MG996R Servo Motor tests. In the LoRa RFM 95 test, it was successful up to a distance of 350 meters, beyond this distance it failed to transmit the signal. Tests such as RSSI, SNR and Delay were also carried out. In the LoRa test, slave1 data was produced -34 to -104 (dBm) at a distance 0 –350 meters and slave 2 data produced (-32 to –107) (dBm) at a distance of (0 –350) meters but at a distance 400 –450 but each slave cannot send, the SNR on slave 1 has 8 data including (9.50 –4.50) dB and slave 2 (9.50 –3.00) dB which is relatively low and the delay of sending depends on the distance and obstacles to sending. Testing the MG996R Servo Motor showed an error (0.07%). Load Cell testing shows errors on Slave 1 (0.27%), Slave 2 (0.07%), and Master (0.20%). And the overall system test shows success and in opening or closing the door latch it can work properly.
