Integrated System of Multi-Location Tank Volume Monitoring Based on NRF24L01Plus

The increase in the number of private vehicles in the community increases every year, with the increase in the number of private vehicles uses causing the need for fuel to continue to increase so that often the supply of fuel at public filling stations (SPBU) cannot serve the needs of the community because the new fuel supply is not proportional to the amount of fuel purchased and causes the fuel stock at the SPBU to run out before the new fuel supply comes. Usually, the measurement of fuel stocks is done manually using the measurement method using a dipstick, because using the manual method the stock of fuel in the tank cannot be monitored in real-time and causes inaccuracies in monitoring fuel stocks. Then a system was designed that has been integrated in monitoring tank volume stock using the HY-SRF05 ultrasonic sensor mounted on a different tank and using the NRF24L01+ PA LNA transceiver communication module. The data read by the sensor ultrasonic HY-SRF05 height sensor for detect volume in the tank which is placed in a different tank will be transmitted by the NRF24L01+ PA LNA module and will be captured by the same receiver, the data will be processed so that it will be displayed on the LCD and the Google Sheet IOT platform and the reading data will be into an excel document so that the results of the reading can be a reference in managing the stock of fuel. By using this method, the tank volume can be monitored in real time.
