Abstract: This paper presents the design and implementation of an Internet of Things (IoT)-based smart office automation system developed to improve energy efficiency, security, comfort, and real-time office monitoring. The proposed system integrates an ESP32 controller with IR, LDR, DHT11, MQ-2 and R307 fingerprint sensors, together with relay modules, an L298N motor driver, a DC motor, a 16×2 LCD and a P10 LED display. Occupancy information is used to automate lights and fans, while environmental information supports temperature, humidity, light and air-quality monitoring. Biometric authentication is used to update office availability, which is displayed outside the office. ESP-NOW/Wi-Fi communication supports wireless exchange of status information between controller and display modules. The supplied project report documents successful hardware and integration testing, including motion detection, environmental sensing, biometric authentication, appliance control, curtain operation, sensor integration and failure handling. The system provides a practical prototype for smart-office and future smart-campus applications.
