The research developed an automated system using an ESP8266 Microcontroller, DHT11 Temperature Sensor, 5V Relay Module, Fan, and Power Supply to control room temperature by comparing room and ambient temperatures and adjusting fan operation accordingly for energy conservation, environmental, economic, and comfort-related benefits of aligning room temperature with ambient temperature.

R2 (two users) had slightly lower temperatures at 33.81°C (PM) and 33.33°C (AM), showing fewer users generate less heat. R3 (no users) showed significantly lower temperatures at 26.87°C (PM) and 26.35°C (AM), highlighting that absence of users leads to lower heat accumulation. ANOVA results show a significant effect of room conditions on temperature but no significant effect of the time of day.
