How to measure temperature using arduino

hi guys in this video i will show you how to measure temperature using arduino
componets needed
1) arduino nano
2)ntc thermistor
3) 10k residtor
4) jumper pins
5)breadboard

Tip: People Always see the thumbnail, preview, channel name, logo and length of the video to determine if they are going to click on the video, and because it can be done in 4 minuets and there are tutorials which show it in less time and provide more information than your video, that would be one of those reasons why this video has less views then others. people want to get it working in small amount of time but your video is over 7 minuets long which at this point people would watch this video if they want nice presentation or some video making technique or for entertaining purposes. so Good Luck on which type of video you want to make, usually entertaining videos make more views, subs, likes but less use.I am not blaming that this video is not good so don't mind me and if anyone found it useful then please reply me so i can know if my reply was usefull to someone's life. Have a good day.

Hey! What should I change to make it work with 5 kOhm thermistor?

[@j.tunoud]

Mister, What if my board is an esp32 and it only supply out a 5V will that effect the accuracy? or what should I change in order to match the one you show

[@YungRu]

thanks, worked perfeclty

[@ElectroRetro]

Glad it helped

Hi. Can i use this with 1k resistor?

[@gabupal1324]

How did you arrive at the formula:
R2 = R1 * (1023 / Vo - 1)
Can you explain this please.

[@ElectroRetro]

It's Steinhart-Hart equation used to convert resistance to temperature.
en.m.wikipedia.org/wiki/Steinhart%E2%80%93Hart_equation

[@gabupal1324]

@@ElectroRetro I am asking about the step before the Steinhart-hart equation, where you calculate the resistance of R2.

[@ElectroRetro]

R2 is calculated by the value of resistor R1, Input voltage Vin, output voltage Vout (the voltage between the thermistor and resistor R1) R2= (VOUT * R1) /(VIN - VOUT).

[@gabupal1324]

@@ElectroRetro So what is the significance of the numbers "1023" and "1.0".

[@ElectroRetro]

Analog values of measured output

[@mohammedmoiz1381]

can you mention which ntc thermistor is being
used here....

[@ElectroRetro]

I am using this ntc thermistor : robu.in/product/b3950-10k-ntc-thermistor-temperature-sensor-525mm-with-xh2-54-connector-with-0-5-meter-cable/?gad_source=1

sir, I want to calculate child body temperature when so please make a video on that.

Sure

How do you know which is + and - on the wire?

[@ElectroRetro]

For NTC resistor there is no + and -

Brother I need a help to built a temperature measurement system?

[@ElectroRetro]

Sure

ah i understand now.

The link for the code tries to execute a JS virus script!

[@ambalapetlover7904]

what about accuracy?

[@ElectroRetro]

+/- 1 degree Celsius

[@ambalapetlover7904]

@@ElectroRetro
thanks for fast reply
i want to make incubator controller using this
can it give accuracy much more???

[@ElectroRetro]

I think this will work fine for the incubator.

[@ElectroRetro]

Or you can use w1209 thermostat. Previously I made an incubator using w1209 and it works.

[@ambalapetlover7904]

@@ElectroRetro
i m already using w1209
but i want to make a fully automatic incubator
commercial controller are costly
i use your code 10 minut before
this work fine for me
only problem is noice problem
temperature reading fluctuate very much
not give me a stable reading

its showing -275.5 -254.2 300.1 and stuff :/

[@ElectroRetro]

Try changing resistors

[@RandomlySelectedUserName]

In the code change float CL values.
