741 Op-amp LM35 temperature circuit DIY

Tishitu explains
This is basic of working with LM35 temperature sensor, which is taken from the LM35 spending and boosted again by the amplifier op-amp. and comparator mode of operation with High output if the sensor is received by ic LM35 high temperature . You can use the output as driver relay, fan , buzzer or other . And if yo want to see modifications LM35 temperature sensor go to our another video using microcontroller

This is amazing video. I have a question can we build a human temperature monitoring circuit on this software.

[@priskangassa3154]

thanks for the video. can i measure a temperature ranging from -50° to 70° with this circuit diagramm ??

[@fatimazahraelbouriki7713]

thank you for this amazing video.
is it possible to add an alarm to this circuit in case the temperature is above a certain value?

[@TarunShrivastava]

Yes, absolutely attach piezo buzzer at ends to led

[@jyothirh6602]

But led is grounded no sir

[@muhammadhaseeb5389]

Is the variable resistor also the feedback resistor?

Thank you for your video. Can I know is it possible to modify this into an ADC system?

[@TarunShrivastava]

Yes, absolutely

[@TasfiqueSarwar]

Thank you for your video.how can i add heater in it? is it possible?

[@TarunShrivastava]

Yes, of course by using relay

[@nurbanu1283]

Thank you for the tutorial. I am given a similar homework and i need the LED to light when the temperature hits 100 celcius. How can i do that?

[@TarunShrivastava]

Glad it helped, well attach high resistance at output or lm 35/34 sensor or change variable resistance 1k to higher value

[@nurbanu1283]

@@TarunShrivastava I figured it out. I fixed the heat on 100 celcius. Once the resistance of potentiometer is above 200, the LED lights up. Didn't need to change anything. Thanks for the response, good luck👍

[@habibashahid6731]

Hey do you have a tutorial on how to build this circuit on a bread board?

[@alanbiju4714]

Can u explain abt temperature to voltage converter circuit using ic 741

[@alanbiju4714]

If u have any data plz provide link

[@mrniceguy4852]

this doesnt work in real life because LM35 cannot output more than 0.5V

[@cesarpena227]

Hello, Do you think it will work if I use an instrumental operational amplifier to amplify the signal of the LM35? I will appreciate your help 🫠

[@mrniceguy4852]

@@cesarpena227 yes it will work
