RANCANG BANGUN PROTOTYPE WATER LEVEL MONITORING PADA FOAM TENDER KANGLIM DI BANDAR UDARA JUANDA DENGAN SENSOR JARAK HC-SR04

Ketersediaan air pada Foam Tender Kanglim perlu dipantau secara cepat untuk
mendukung kesiapsiagaan kendaraan dalam penanggulangan keadaan darurat.
Penelitian ini bertujuan membuat prototype Water Level Monitoring menggunakan
sensor jarak HC-SR04 dengan komunikasi ESP-NOW sebagai media pengiriman
data antara ESP32 transmitter dan ESP32 receiver. Metode penelitian meliputi
perancangan, perakitan perangkat keras, pembuatan perangkat lunak menggunakan
Arduino IDE, serta pengujian sistem. ESP32 transmitter berfungsi membaca
ketinggian air pada tangki, kemudian mengirimkan data ke ESP32 receiver melalui
ESP-NOW. Data yang diterima ditampilkan pada LCD I2C, sedangkan LED
digunakan sebagai indikator level air dan buzzer sebagai alarm ketika ketinggian
air kurang dari 3/4% kapasitas tangki. Hasil pengujian menunjukkan bahwa
prototype mampu membaca perubahan ketinggian air, mengirimkan data secara
nirkabel, serta menampilkan informasi kondisi air secara real-time. Dengan
demikian, prototype yang dibuat dapat membantu proses pemantauan ketinggian
air pada Foam Tender secara lebih praktis dan efisien
Water availability in the Kanglim Foam Tender needs to be monitored quickly to
support vehicle preparedness in emergency situations. This research aims to create
a Water Level Monitoring prototype using an HC-SR04 proximity sensor with ESP
NOW communication as a data transmission medium between the ESP32
transmitter and receiver. The research methods include design, hardware
assembly, software development using the Arduino IDE, and system testing. The
ESP32 transmitter measures the water level in the tank and then transmits the data
to the ESP32 receiver via ESP-NOW. The received data is displayed on an I2C
LCD, while an LED serves as a water level indicator and a buzzer serves as an
alarm when the water level falls below 3/4% of the tank's capacity. Test results
show that the prototype is capable of detecting changes in water level, transmitting
data wirelessly, and displaying real-time water condition information. Thus, the
prototype can facilitate the process of monitoring water levels in the Foam Tender
more practically and efficiently
