Sistem Pemantauan Kualitas Air Sungai Berbasis Iot Menggunakan Mikrokontroler Esp-32

Abstract

Water was an essential resource for life on earth. Where water was needed according to the function. Water was needed by living things to survive and water was also needed for the daily activities of living things. The closest water resource was the river. Rivers have many functions for humans and the ecosystem in the river. However, most rivers have been polluted and are no longer suitable for use. So in this research a tool will be developed that was able to monitor the quality of river water based on IOT, the function was to monitor the three parameters, namely, pH, turbidity, and temperature. The input sensors used in this study are the pH meter sensor SEN0161V1, the Turbidity meter sensor SEN0189, and the Pt100 temperature sensor. Then the input from the sensor was processed by the ESP-32 microcontroler which is connected to the internet network via a 4G router and the results will be displayed on the smartphone via the Blynk application. Measurements were made at three locations. That was, the first location was on the lake around Puspitek Housing and the measurement results obtained have an average of: pH (6.37), Turbidity (1283.1 NTU), and temperature (32.05℃ ). The second location was on the river around Jalan Puri Serpong and the measurement results obtained have an average of: pH (6.26), Turbidity (1340 NTU), and temperature (28.87℃ ). The third location was on Sungai Taman Kota 2 BSD and the measurement results obtained have an average of: pH (6.51), Turbidity (1372 NTU), and temperature (29.69℃).
