Implementation of Water Level Monitoring Device Using ESP32 CAM: Contributing to SDG 11
Mojokerto, July 16, 2024 — Students from Universitas 17 Agustus 1945 Surabaya (UNTAG), Bessotu Putra Herani and team, along with Lutfi Agung Swarga, S.T., M.T., as the supervisor of the community service activities during the Kuliah Kerja Nyata (KKN) program, which was held in Bakalan hamlet, Gondang district, Mojokerto regency.
Bakalan hamlet has several tributaries originating from a major river that flows in from the southeast of Bakalan village. The river, with its fluctuating discharge depending on rainfall and seasons, prompted us to implement a technology to monitor the water level in the rivers within Bakalan hamlet. This device not only monitors water levels but also visually assesses the water’s color condition.
Utilizing the ESP32 Cam microcontroller, students created a device akin to CCTV that serves as an alternative to conventional CCTV systems. Local residents can easily monitor using this device with their smartphones or laptops as long as the device is connected to Wi-Fi and they can open a browser. The ESP32 Cam was chosen for its built-in Wi-Fi, Bluetooth, and SD card module features. It can also be programmed and supplemented with modules according to needs, such as ultrasonic sensors, infrared sensors, and others.
This activity is expected to assist the community in fulfilling SDG 11, which aims to make cities and human settlements inclusive, safe, resilient, and sustainable by utilizing river water as an irrigation source for the village’s rice fields.
