Industrial Temperature Controller Using Microcontroller

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.

Industrial temperature controller using microcontroller.

We here use ic ds1621 to sense temperature. A document gaining is an imperative role in industry in order to insure the quality of service. Pic 18f45k22 is the brain of this automatic temperature. An 8051 microcontroller is used for this purpose.

Temperature sensor measures the. Temperature controlled dc fan. 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. It is also used to show the current temperature on an lcd display.

This paper presents a pc based temperature pressure and humidity watching and control system using microcontroller. Many industrial machines operate for decades so the controllers must also. It also displays the temperature on an lcd displays in the range of 55 c to 125 c. Our project aims to monitor and control the temperature of devices as per it s requirements in the industrial use.

Users therefore need long term support. 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.
