Abstract :
In this chapter the problems faced by AA Bere Tallo Airport when landing the
PAPI (Precision Approach Path Indicator) light unit which is used to give an indication
to aircraft have not been realized by ATC (4ir Traffic Control), so they do not know the
PAPI. functioning properly or experiencing problems.
A tool for design of papi ( precission approach path indicator ) lamp monitor
device with current sensor and wireless delivery. ACS712 current sensor to detect
current This tool can be used to determine whether the PAPI system can function
properly. The tool that has been made consists of several components, namely the
ACS712 Arduino nano current sensor, lights, relays, nRF24L01 Module, Arduino LCD
as the main control on this tool to process data from the ACS712 current sensor then the
results will be displayed on the LCD and will also be sent by the nRF24L01 module. to
ATC.
Based on the results of tests carried out three times the ACS712 current sensor
and the nRF24L01 module, it was found that the difference in the average error value
was 1,4 %.
