Since different temperature sensors have been introduced that most famous of it is that a lm35 IC IC is analog.

But here in an IC thermometer for you to introduce that this is the digital IC is to have the IC 3 and the base is the basis of the temperature information as to the output data. (although not directly).

In this section view of the sensor base Vtrtyb Vnv you are shown.

1: vcc

2: gnd

3: output

Two +5 volt supply base and we exit the third base is normally about 4 kHz frequency provides the temperature that it duty-cycle changes. (Order from Dave T Time Cycle duty_cycle hight than being a total pulse time pulse is a cycle.) In the temperature data in this cycle is going Duty_cycle.

This temperature sensor can be about -45 to +130 centigrade, with over 0.005 Rzvlyshvn centigrade to measure.

Manufacturer under a formula such as photos for this IC is specified.

According to the formula that if we dc (duty-cycle) we have we achieved through the temperature formula that bring more Description will be complete.

This different type of IC is made in Yazd TO92 type there like the lm35 IC transistors are formed.

About nutrition must say that this IC can be voltage of 4.75 volts to 7.2 volts can connect to the best voltage is 5 V and current consumption of the IC 160 to 200 micro amps are.

IC output frequency between 1 to 4 are Kylvhrtz IC and output impedance is 200 ohm. The IC thermometer is suitable for micro-processor are no adc such as the 8051 can easily work with this IC do.

Other advantages of this IC is that you cable over 20 meters long is connect it to the micro.

Reduce noise on the circuit before the circuit can use the following institutional Dytashyt the IC is given.

And the end price of a CD in Yazd is 3000 USD.

Active in program

In this project and the micro Atmega8 BASIC programming language is used.

Get Dyvty Cycle of Self 1 is used to form the micro Hight time being and being a low output cycle counts are then obtained with two time with together and then being on time Hight total time a pulse that divided thus duty_cycle are achieved.

According to the following formula to perform the steps.

1: t (hight) + t (low) = T

2: t (hight) / T = DC

3: Dc = DC - 0.32

4: Temp = Dc / 0.0047

In total with this IC is very comfortable, but if you have any problems you can it make the Forum raised.
