Smart AI Air Conditioner Controller System

  • Abstract:
  • This paper presents a Smart AI Air Conditioner Controller System, an IoT-based solution that transforms any existing split air conditioner into an intelligent, sensor-aware, and remotely managed climate control system. The system employs an ESP32 microcontroller as the edge computing node to collect real-time data from DHT22 (temperature/humidity), INA219 (power monitoring), and PIR (occupancy) sensors. A Python Flask server implements a rule-based decision engine to determine optimal AC operating parameters—on/off state, temperature setpoint, and fan speed—returning control commands via HTTP/REST. Physical actuators include a relay for compressor control and an L293D-driven fan motor with proportional PWM speed control. Telemetry data is logged to CSV for future machine learning model training. Testing over 24 hours demonstrated reliable operation with 8,638/8,640 rows logged successfully, mean HTTP round-trip latency of 8.7 ms, and estimated monthly energy savings of 81 kWh compared to conventional AC systems. The architecture is designed for seamless upgrade from rule-based control to machine learning without hardware or protocol changes.
