Industrial Temperature Controller Using Microcontroller

Temperature sensor measures the.

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. 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. A document gaining is an imperative role in industry in order to insure the quality of service. This practical temperature controller controls the temperature of any device according to its requirement for any industrial application.

We here use ic ds1621 to sense temperature. Our project aims to monitor and control the temperature of devices as per it s requirements in the industrial use. It also displays the temperature on an lcd displays in the range of 55 c to 125 c. 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.

Many industrial machines operate for decades so the controllers must also. The block diagram of the temperature controlled fan using a microcontroller is shown in the above figure. Temperature controlled dc fan. 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. This paper presents a pc based temperature pressure and humidity watching and control system using microcontroller.
