Abstract

The increasing use of household electrical appliances can increase the electrical load, particularly in households with low electrical capacity. Operating a water pump simultaneously with high-power electrical appliances can cause the electrical load to exceed the available capacity and potentially activate the Miniature Circuit Breaker (MCB). This study aims to design and develop an ESP32-based water pump control system to prevent excessive electrical loads in low-power households by controlling pump operation based on water level, electrical power consumption, and operating time.
The research method used was Research and Development (R&D), consisting of the stages of design, development, implementation, and prototype testing. The system was developed using an ESP32 integrated with an HC-SR04 ultrasonic sensor, PZEM-004T V4.0 energy sensor, DS3231 Real-Time Clock (RTC) module, relay, 20×4 LCD, keypad, and EEPROM. The system implements a hysteresis method, Peak Hour feature, Initial Filling Target feature, and pump operation restrictions based on the available electrical power limit.
The test results showed that the HC-SR04 sensor had an average error of 5.66% in water-level measurement, with higher errors occurring at low water levels. The PZEM-004T V4.0 sensor had average errors of 0.19% for voltage, 10.44% for current, and 15.78% for power. Although errors were observed in the sensor measurements, the PZEM-004T V4.0 was still able to provide information on changes in electrical power consumption used as an input for the control system. The prototype was able to delay pump operation when the electrical power consumption reached the safe power limit and implemented time scheduling and an initial filling target to control pump operation. The testing also revealed limitations in keypad sensitivity and LCD display stability, where the LCD occasionally experienced blank or hang conditions, particularly when the relay changed its operating state. Overall, the prototype was able to perform pump control based on water level, electrical power consumption, and operating time according to the designed algorithm.
