Working of automatic ac temperature control system.
Automatic temperature control system circuit.
In his design the temperature control system can only control a single heat source.
Here the temperature is the output to be controlled.
Pic 18f45k22 is the brain of this automatic temperature controller system.
The temperature of the area is measured using an analog temperature sensor the lm35 precision integrated circuit temperature sensor is used for this.
Where the temperature is automatically adjusted as per the input settings.
Now place the circuitry opposite to your air conditioner and you notice the ac s temperature getting controlled based on the rooms temperature.
If the desired value is higher than the measured value then the heater is turned on to heat the area.
Hedges invented an automatic temperature control systems intended at automatically controlling the temperature of an object a part thereof or a region so as to continuously maintain the said temperature at a constant value.
Module in tunnel microwave heating system 5 a the integrated system of smart tudungsaji consists of a precision temperature controller by using embedded temperature sensor lm35 for input the atmega 328p system 6 an automatic temperature control system by microcontroller for data interpretation and 2 bulbs as the using zilog s real time kernel rzk can be used to output.
The circuit is using a microcontroller to control the fan according to the temperature variation.
Basically the circuit switches on a toy motor fan connected to the motor driver whenever heat is applied to the temperature sensor unit using say a burning matchstick.
A temperature controlled system is a type of control system that automatically controls the temperature of an object or an area.
When your code and hardware is ready upload the code to your board and you should notice the oled displaying something similar to this.
However it is difficult to attain temperature control having simultaneously and in combination of the desirable features of large capacity high response.
Also the temperature of the system is measured using sensor.
The wind from the motor fan would blow off the matchstick and switches off itself automatically.
The system measures the temperature from the integrated circuit ic lm35 where it will control the fan according to the setting values in the programming.
The microcontroller reads the temperature continuously and compares it with the desired value.
Automatic temperature control is a microcontroller based circuit which is used to maintain a temperature specified by the user.
4 design of automatic temperature control circuit the block diagram of the system is shown in figure 1.
We commonly use temperature control systems in air conditioners refrigerators geysers etc.
The circuit is using a microcontroller to control the fan according to the temperature variations.
