دمت گرم بابت ویدئو و تلاشت که هم گرافیک قشنگی ساختی و هم خوب توضیح دادی. تعجب نکن از رو لحجه باحالت فهمیدم ایرونی هستی. ولی باز دمت گرم ، میدونم چقدر ساخت همچین ویدئویی زمان بره
Hi. I'm a bit confused about how to convert this ADC Analog to PPM with MQ3 Sensor.. The default result is about 120 - 200 clean air reading. I just dont know how to calculate it, or if there any formula to get the right PPM, please tell me. I plan to use MQ3 for detect Ethylene gas. Thank you.

خیلی عالی
Very great
Thank you
Hello
Very nice tutorial ✨
Please in the calibration code, how to procede when calibrating it for CO gas
how do you feed 1.4v with the pcb sensors?

i get the result from your tutorial
sensor_volt = 0.73
RS_ratio = 5.87
RS/R0 = 6.45

what specific arduino uno model was used?
What unit value does mq9 shows in a monitor? Is it in ppm already?
1 mg/L is 1 ppm...
24-48 hours to warm up and get ready to use. This cant be serious
Why do I think you're Persian?
This is a MOS sensor and not an electrochmical sensor. YOu can finde more infos here: ruclips.net/video/hX5kLqPe8nc/видео.html
