Field of Invention:
This invention relates to temperature maintenance inside the room where the A/C duct is installed.
Background of the invention
The present invention relates to a technique which is preferred suitably in the field of seminar halls, class rooms, auditoriums and the places where the A/C duct damper is installed. The invention mainly concentrates on the area where the temperature is to be maintained constantly. The temperature sensor is used to detect the temperature inside the room as well as the temperature inside the duct damper. The place where the temperature is to be controlled is under the control of this invention. The invention controls the temperature and maintains the constant temperature inside the room. The motor which is used in this invention controls the rotation the duct damper blade and allows the particular temperature on the basis of room temperature and the A/C which is flowing inside the duct damper is monitored by the pressure sensor, if the particular limit exceeds then the valve opens and A/c is sent back to the plant. This is controlled by a pressure sensor. The places like auditorium or a seminar hall, where we spent the whole day for particular event is to be maintained. If the temperature is not maintained constantly the persons who is inside the auditorium or in seminar hall feels a bit uncomfortable. If the temperature a bit more it creates lot of health issues. Those health issues are totally neglected by this invention.
Summary
In order to achieve the objective described above, according to the aspect of this invention, it is provided with instrumentation and embedded technologies. Electrical technologies used to detect the temperature and rotate the blade to achieve the properties of the invention.The signal sensed by the sensor is processed and controlled by using the interfaced Arduino microcontroller with the appropriate sensors.

Detailed description
Figure 1 is the block diagram of the present invention explaining the above contest is in accordance with the present invention. An inspection system consists of the microcontroller(l), Temperature sensor(2), pressure sensor(6), servo motor(4), duct damper blade(5), LCD display(3), A/C duct valve(7). The temperature sensor (2) senses the temperature and sends it to microcontroller (1). The microcontroller (l)sends signal to the LCD (3)to display the temperature, then the signal is passes to the servo motor(4) and it reads the signal and it responds by rotating the duct blade(5) for particular angle. Then the microcontroller (1) receives signal from the pressure sensor(6) which is responsible for monitoring the pressure inside the duct damper. If it attains the particular limit then the duct valve (7) opens and the

Then the microcontroller (1) receives signal from the pressure sensor (6) which is responsible for monitoring the pressure inside the duct damper. If it attains the particular limit then the duct valve (7) opens and the temperature is sent back to the plant. The valve opens when the pressure attains the limit and the valve is connected to the plant (chill out) so the excess A\C is sent back to the plant which the efficiency of the plant is increased. The supply is given and the power consumption is very low and the required output is taken out.
5. CLAIMS
We claims
1. The system consists of temperature sensor(2), microcontroller 1), pressure sensor(6) with LCD display(3)
2. As per the claim 1, the room is fully monitored by the temperature sensor (2), and it covers to a range of 100m and measures the temperature range up to 80° C. Each phase consists of servo motor (4), duct damper blade (5), pressure sensor (6). This forms a closed loop configuration.
3. As per the claim 2, when the temperature reduces from room temperature it means the temperature of the duct damper(5) is not controlled then the microcontroller I) passes the signal to the servo motor(4) and rotates the blade and reduces the A/C flow into the room.
