Users therefore need long term support.
Industrial temperature controller using microcontroller.
This paper presents a pc based temperature pressure and humidity watching and control system using microcontroller.
An 8051 microcontroller is used for this purpose.
It also displays the temperature on an lcd displays in the range of 55 c to 125 c.
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.
Temperature sensor measures the.
This practical temperature controller controls the temperature of any device according to its requirement for any industrial application.
Many industrial machines operate for decades so the controllers must also.
We here use ic ds1621 to sense temperature.
The block diagram includes power supply rst circuit 8051 microcontrollers lm35 temperature sensor 8 bit adc l293d motor driver dc motor 7 segment display i p switches.
Pic 18f45k22 is the brain of this automatic temperature.
A document gaining is an imperative role in industry in order to insure the quality of service.
Automatic temperature control is a microcontroller based circuit which is used to maintain a temperature specified by the user.
It is also used to show the current temperature on an lcd display.
Original equipment manufacturers must take a long term view of the products they use in their machines and need to be ready when a customer wants to buy parts for a system installed in the 1990s or even earlier.
