Please tell all the components

[@harshasrisampath8181]

Sir i done everything thing like u but the display is not showing the co2 level

[@m34adn56]

The thing is , the sensor's output is nothing more than ADC value itself which this is mapped from 1023(max res for an 10bit device) to 5000. There are proper equations which let you to know a specific gas concentration. But first there is an calibration procedure for that. And remeber , each sensor is a sensor , so the values on output may be different!

[@m34adn56]

And yeah you can use ADC values to determine some gas "variation" , but nothing more :)

[@JustDoElectronics]

yes you are right :)

[@SonVu-zh6gh]

What software you use to simulate circuit diagram? Please help me

[@JustDoElectronics]

Simple paint software

[@SonVu-zh6gh]

I can't find it, can you please give a link to it, I mean software at 0:50

[@lil_tesla_69]

I've used a i2c module what to do

[@JustDoElectronics]

Change The code

[@AleksandrIvin]

Great job! Is this sensor really good with CO2?

[@Turissss]

I have the same question.

[@chandnikumari1271]

How to do physical wiring it's so tough for beginners

[@JustDoElectronics]

Chek website is explain properly

[@chandnikumari1271]

​@@JustDoElectronics bro wiring smjh nhi aa rha pls thoda explain krdo it's kinda urgent

[@chandnikumari1271]

Sir nhii chal rha circuit help krdo coding ke baad bhi on nhi ho rha

[@JustDoElectronics]

@chandnikumari1271 ok contact in what’s app

[@user-tu4gm1wl2m]

Проверил. Схема работает. Но датчик реагирует на все что угодно кроме co2 :/

[@JustDoElectronics]

i Don't Understand please talk in english

[@user-tu4gm1wl2m]

The sensor reacts to flammable gases . co2 does not display

[@JustDoElectronics]

​@@user-tu4gm1wl2m Why sir in my side is working properly

[@JustDoElectronics]

@@user-tu4gm1wl2m ooo ok can you send me your sensor photo

[@JustDoElectronics]

@@user-tu4gm1wl2m i will chek it

[@Ia-zx1qg]

u had coding for this

[@4_nd_1]

u can check the link in description
