How to Make a Simple Pulse Oximeter at Home

[@kumarnitnarwade6656]

Dil se salute sir aapke hr ek products or project ke liye. I request to everyone please share this video. Sir thanks for this needful device.

[@yupingliao4078]

यह सटीकता बहुत अच्छी है, इसका उपयोग अस्पतालों में किया जा सकता है, और यह बाहरी उत्पादों के बराबर भी है।

[@Sidtube10]

This is an amazing instructable! Nicely made video as well! Liked the desi jugaad done as well - haha!!

[@pavanlakhe3987]

Sir this is nothing but one type of integrity 😘😘 It is because of people like you that today the reality for India rests. 🙏🙏🙏❤️❤️ Intresting 👍

[@ShubhamSuresh]

So nice of you

[@symphonyeducationplatform7560]

Very very very informative..Simple pulse oximeter. Plz share economical cost of this project with market price. Thanku and all the best..

[@ShubhamSuresh]

you can make it around at cost of 370 INR

Hello, I made this circuit on a breadboard. I see the insert finger text on the OLED screen, but the LEDs and IR receiver do not work. What could be the reason?

[@ahmed-noorawale5352]

Great improvising my friend, +1

[@akhaqan]

Very nice work. Can it be programmed to display O2 two digits after the decimal e.g. 96.55

[@ShubhamSuresh]

yes it could be

[@kumarnitnarwade6656]

Sir circuit diagram terminal hai wo thoda clearly dikh nhi raha hai agr aap description box me circuit diagram provide kr sakte ho .

[@ShubhamSuresh]

circuit diagram ke liye description me link diya h

[@soriatel]

and the union of anodes of the LEDs where they are connected?

[@r.pranay4486]

Superrrrrr bro👏👌

[@surajmandaogade1891]

Sir nice work

[@ShubhamSuresh]

thanks

[@r.pranay4486]

Should we connect vcc to that red wire that is positives of both?

[@ShubhamSuresh]

Yes connect it to the vcc

[@r.pranay4486]

Ok bro thank you for your helpful replies.👏👏👏👍👍👍

[@ShubhamSuresh]

Always welcome

[@SomchaiLoey]

is photo sensor the same as ir receiver ?

[@r.pranay4486]

Does inside red led should glow when we insert the finger

[@ShubhamSuresh]

yes

[@r.pranay4486]

Is the pins of it led and red led are correct?

[@ShubhamSuresh]

If you have problem with LEDs, make the connections as follows. Make sure negative end of LED connected with collector of transistor and positive end of both LED to the vcc.

[@prashantbramhatkar5260]

How do you calibrate it with professional one

[@ShubhamSuresh]

Hi Prashant please check my on Instructables for more details: www.instructables.com/DIY-Pulse-Oximeter/

[@r.pranay4486]

Why to scrap that photodiode and ir led

[@ShubhamSuresh]

photo diode grinded so that it can receive maximum light form both LED.

[@arunarya7161]

👏👏

[@charandommalapati9001]

I have connected all these connections using breadboard , the red led is on but it isn't showing any reading in oled when I inserted my finger it's showing only insert finger . The photo diode is not sensing anything how can I rectify this

[@ShubhamSuresh]

check polarity of photo diode. and block any other light source.

[@bendahmanebouteina]

I am having the same problem as you, did you manage to find a solution ?

[@gabrielarosero1962]

Hola, pudiste solucionarlo?

[@soriatel]

Como identificar un fotodiodo?

[@AyeshaWajid-w2s]

Sir ... Can we use aurdino nano instead of aurdino mini pro .... If yes ... which model of aurdino nano

[@ShubhamSuresh]

Yes you can.

[@arasitininadamar8179]

Sir can you make the circuit simulation on Proteus and share it to me?

[@made2automate]

❤️❤️

[@prashantbramhatkar5260]

Is it showing real readings?

[@ShubhamSuresh]

Yes it is.

[@asanjuprajapatidosti8803]

Sir banaya acha lekin ye banake kon use karega Yaha vaha saath le jana ho to kon le jayega ye Mere hisab se ye kaam me nahi aayega koi iska use nai karna sahega kuki new market me mil raha he to

[@ShubhamSuresh]

It's just for educational purpose.

[@ninobba2554]

hy sir, please help me its just show insert fingure and dont show any result. any solution??

[@megnus51]

I can't make it work except insert finger, did you ever get it fixed?

[@ninobba2554]
