The systems is developed using a LM35 temperature sensor, ATMEGA328P micro controller, BC547 transistor, Arduino chip and a TSOP 382 Infrared receiver . LM35 senses the ambient temperature and TSOP 382 infrared light receives signal from the remote. The two signals get to the microcontroller which is the heart of the system. The Arduino Uno software is programmed inside the microcontroller which senses temperature and control the speed in response with the set temperature. The 2 digit 7 segment LED (Light Emitting Diode) display temperature sensor readout. Keywords: Arduino Uno, microcontroller, electric fan, temperature sensor, infrared light INTRODUCTION Today, electric Fan is used for various purposes, especially in Africa. It is used to control the room temperature. Over time, the cooling requirement of our body varies, and this usually involves the tedious task of adjusting/regulating the speed of the Fan. Many people, especially the physically challenged are affected most because of the inconveniences associated in changing the Fan speed level manually. This could force them at times, to let the Fan rotate at a speed that does not reflect their current need [1,3]. Generally, the Fan is left to run constantly at a very fast rate than required. It is a stressful process to get up (usually at night) to adjust the Fan speed level manually when the room temperature changes. As stated earlier, the disabled/physically challenged persons are most affected. Though, there are two perceptions to this problem: more electrical energy is being spent than necessary and awkwardness are suffered with frequently manually regulating Fan speed with varying room temperature. Hence, an efficient and reliable closed loop control system that automatically changes the Fan speed level according to the change in room temperature is built to solve the problems and shortcomings associated with manual method of Fan speed control [5]. An intelligent temperature monitor with remote Fan controller that automatically changes its speed level, according to varying ambient temperature is developed. The primitive ways of switching Fan involves switching the button to control the speed, there is no way the temperature will change speed with such approach, and therefore there is a need to create a system that regulate the speed as the ambient temperature change. In this system, the temperature is measured by a suitable sensor which can be detected by the microcontroller. The microcontroller compares the temperature signal to the desired temperature and
