Automatic Room Temperature Control System

Automatic room temperature control system ut ilized temperature sensors to detect the temperature of the server room.

Automatic room temperature control system.

The user enters the reference temperature by keypad and then the microcontroller turn on and off the heater or cooler when the temperature is too hot or too cold. Automatic temperature control system. This is an air conditioning system which monitors the room temperature and controls the circulation of fresh air inside the room without human intervention. Dedicated control over room temperature is not only a key issue in providing work conditions that ensure employee satisfaction and hence increased work output.

The temperature sensor lm35 is very accurate whose output is directly proportional to its surrounding temperature. The design considered the flexibility of using a microcontroller pic16f876a along with other peripheral devices such as lm35 temperature sensor lcd display unit to form all encompassing single system. The input of the system is the required temperature. Automatic temperature control is a microcontroller based circuit which is used to maintain a temperature specified by the user.

For every 1 c of rise fall in temperature the output voltage of the sensor varies by 10mv. Automatic room temperature control. This design uses a microcontroller and a temperature sensor to monitor and control the temperature of a room. This circuit maintains the temperature of the system in a particular range.

A closed loop automatic control system for the temperature control in a room or enclosure is shown in figure. The controlled variable in this case temperature is measured by a suitable sensor such as a thermocouple rtd thermistor or infra red pyrometer and converted to a signal acceptable to the controller. Automatic room temperature control 1. It is now a health and safety issue.

The controller compares the temperature signal to the desired temperature setpoint and actuates the final control device. Automatic control plays an ever increasing role in human way of life. The concept of this paper is to create an automatic temperature control system to control the temperature of a system. When the current temperature exceeds the set point.

At room temperature the output of the sensor would be a stable value. The system is the required temperature. Contents problem statement introduction methodology circuit diagram components applications conclusion references 2. Intermediate full instructions provided 30 minutes 4 235.
