Microcontroller and Android HMI Based Water Level and Control System

Abstract

Water is a basic human need in daily life. The use of water is used for various household needs for example for consumption, bathing, washing and so on. At present there are still many people who use water pumps to fill water reservoirs at home or in office buildings that are filled manually, so that problems often occur such as the level of water in the reservoir where water is unknown, it is possible that the situation of reservoirs can occur overflow or empty. Utilizing technology in this research will create a tool used to control the water level in the reservoir, which is "Microcontroller-Based Water Level Control System and Android HMI" which is an alternative in controlling and monitoring the water level in a reservoir automatically using an Android Smartphone. This tool is used to control and monitor water reservoirs automatically via Android HMI so that it can be controlled remotely. This tool is designed using a NodeMCU ESP8266 Microcontroller, a relay module that functions to turn on and turn off the pump, and one sensor, the HC-SR04 Ultrasonic Sensor which functions to measure the water level in the reservoir. And the android application used is Cayenne. The test result data is shown in the cayenne application in the form of setting the water height setpoint, the ON / OFF pump indicator and the height value in units of percent (%) and centimeter (cm).

Evaluation of Water Level in Flowing Channels Using Ultrasonic Sensors

“…Some important considerations about the use and applicability of the ultrasonic sensors used in this study can be seen in water level monitoring in reservoirs [11][12][13][14][15][16][17]. To evaluate the accuracies of the measured levels during monitoring, Drage et al [18] constructed a low-cost (between USD 150 and 225) real-time groundwater level monitoring network for domestic water wells, which has a similar characteristic to reservoirs, and compared the average absolute level errors to those of linigraphs less than 0.02 m. Sahoo and Udgata [19] developed a new low-cost neural-network-based system to increase the accuracy of the water level measurement using the HC-SR04 sensor for storage tanks at different depths.…”

“…The association of Arduino and ultrasonic sensors, especially the HC-SR04 sensor model, is used to monitor water levels in reservoirs [11][12][13][14][15][16][17][18][19][20], where the water surface is smoother due to the lack of turbulence. Thus, because the surface is always regular, the measurement tends to be more accurate and stable.…”

Smart Solar Tracker and Energy Control Based on Internet of Things (IoT)

“…The research conducted is an IoT development with an arduino ESP8266 which functions as a wifi module, (Siswanto, S. Et al, 2020) (Lestariningsih et al, 2019) (Eteruddin, Setiawan, and Atmam, 2019) (Ningsih, 2020) and iOS platforms using Blynk and Arduino-compatible Android, Raspberry Pi (Artono, and Susanto, 2018). The power source is useful for converting solar energy into electrical energy in this study uses a PV system so that panels are more effective in absorbing energy, a tracker system is implanted to be able to follow sunlight using an LDR sensor.…”
