Abstract: — This work introduces a dual-controller architecture designed for real-time supervision and control of a single-phase induction motor. The system consists of two separate modules: a monitoring unit powered by the Node MCU (ESP8266) and a control unit utilizing the Arduino Uno. The monitoring section collects essential electrical parameters—voltage, current, power, power factor, and frequency—via the PZEM-004T sensor. Additionally, it monitors the motor's temperature using a DHT11 sensor and determines rotational speed (RPM) through an infrared (IR) sensor. These readings are shown on a 16x2 LCD with I2C interface and are also transmitted to the Blynk platform for remote access over Wi-Fi. The control unit is responsible for adjusting the motor’s speed using a TRIAC-based AC dimmer, with dimming levels (ranging from 0 to 100%) provided through the Serial Monitor. Directional control is achieved using command characters: 'F' for forward, 'R' for reverse, and 'S' for stop. To safeguard the motor, a 30-second delay is enforced during direction changes to minimize mechanical strain. The developed system offers an effective approach for smart motor management, combining both on-site display and remote control capabilities Keywords— Induction motor, real-time monitoring, speed control, Arduino Uno, NodeMCU ESP8266, PZEM-004T, DHT11 sensor, IR sensor, AC dimmer, TRIAC, LCD display, Blynk IoT, motor direction control, dual controller system, single-phase motor.
