Abstract

Meteran air digunakan untuk mengukur jumlah volume (m^3) air yang digunakan. Namun, meteran air yang digunakan memiliki kelemahan yakni lokasi meteran yang sulit dijangkau dan kurangnya transparasi proses pencatatan dan penagihan. Maka dari itu, dibutuhkan meteran air digital yang mampu mengukur volume air secara real time untuk mempermudah dalam pencatatan dan mengetahui konsumsi air di aplikasi. Meteran air dimodifikasi dengan menambahkan sensor hall effect dan magnet untuk mengukur putaran pada display. Putaran ini akan dikonversi menjadi volume air. Sensor YF-S201 digunakan untuk membandingkan hasil pengukuran dengan meteran air yang dimodifikasi. ESP32 sebagai microcontroller untuk data processing dan mengirim data ke internet. Didapatkan bahwa akurasi pengukuran rpm variasi bukaan katup penuh sebesar 99.52% dan variasi bukaan katup setengah sebesar 99,42%. Nilai rotasi yang dihasilkan ketika air melewati meteran air berbanding lurus terhadap volume yang melewati. Didapatkan nilai meter kubik per rotasi adalah 0,000034. Sensor YF-S201 dalam mengukur volume memiliki akurasi sebesar 99,14% dengan kalibrasi faktor 6,5. Hasil pengujian sistem dan data logger yang dilakukan menghasilkan nilai akurasi pengukuran volume menggunakan sensor hall effect sebesar 98,73%. Namun, sensor YF-S201 memiliki akurasi yang kecil yaitu 69,9%. Pengujian pengiriman data dari ESP32 ke aplikasi didapatkan bahwa ketika pengiriman data pada variasi 150 m dengan mengakses aplikas menggunakan tiga gawai secara bersamaan dengan rata-rata pengiriman data 4.26 detik. Sedangkan pengiriman data terlama ketika pengujian pada jarak 50 m dengan menggunakan dua gawai secara bersamaan untuk mengakses aplikasi dengan rata-rata pengiriman data 12.64 detik.

Water meters are used to measure the volume (m^3) of water used. However, the water meters used have weaknesses, namely the location of the meter which is difficult to reach, and a lack of transparency in the recording and billing process. Therefore, a digital water meter is needed that is capable of measuring water volume in real time to make it easier to record and determine water consumption in the application. The water meter was modified by adding a hall effect sensor and a magnet to measure rotation on the display. This rotation will be converted into water volume. The YF-S201 sensor is used to compare measurement results with a modified water meter. ESP32 is a microcontroller for data processing and sending data to the internet. It was found that the accuracy of rpm measurement for full valve opening variations was 99.52% and half valve opening variations were 99.42%. The rotation value produced when water passes through the water meter is directly proportional to the volume passing through. The cubic meter value per rotation is 0.000034. The YF-S201 sensor in measuring volume has an accuracy of 99.14% with a calibration factor of 6.5. The results of the system and data logger tests carried out produced a volume measurement accuracy value using a hall effect sensor of 98.73%. However, the YF-S201 sensor has a small accuracy of 69.9%. Testing of sending data from the ESP32 to the application found that when sending data at a variation of 150 m by accessing the application using three devices simultaneously the average data delivery was 4.26 seconds. Meanwhile, the longest data transmission was when tested at a distance of 50 m using two devices simultaneously to access the application with an average data transmission of 12.64 seconds.
