Designing a Computer Network Server Room Temperature Control System for a Commercial Bank

— This research paper is based on an automatic temperature control system that automatically adjusts a computer network server room system in response to the surroundings' ambient temperature, in order to maintain it at an optimum range. A temperature control system can be realized in different forms, e.g. as an automated fan that is controlled by a temperature sensor, with the use of a fully hardware design. In this project, the researcher uses a predesigned temperature sensor circuit which monitors the temperature variations of its surroundings. The weak signal produced by the temperature sensor is then strengthened using an amplifier to enable it to drive the output section, which in this case is a fan. Pulse width modulation (PWM) is the technique is used in this case. The heat applied to the temperature sensor, respectively determines how the fan automatically responds by increasing or decreasing its speed thereby affecting the overall temperature of the server room. This system can be handy in cooling various electronics devices, by controlling fan speed whenever heat dissipation increases.
