in this video, I will show you how to measure current with only simply component and your Arduino
------------------------------------------------------------------------------------------------------
the example used in this video can't measure more than 5 amps
DON'T USE IT ON AC!!!
the output voltage maybe affected because of 1-ohm resistor
THIS IS AN EXPERIMENT !!!!

hello, your video was very informative. I have a doubt that we have done the calibration for 1 single value, what if we have different load at different instant, then how we will do calibration?

Great video! Can you measure currents up to 30-40 amps in this way or would you need a shunt resister to handle this amount of current? If you can what size resistor would you need ohms? and watts?

The DC Current per I/O Pin on the Arduino UNO is 40 mA. More than that and you will damage the microcontroller. So you range (30-40A) is 1000x the limit.

What is the value of the resistance ?? I want to measure current around 1.5 A at max
@EslamsLab
@EslamsLab 5 років тому
If at max you can go with a resistor up to 10 ohms But remember high resistance will give you high resolution but limited scale

@EslamsLab 6 років тому
+Electronic & Solar Power sure but you should know first your charger current by using multimeter Then choose the right resistor to sense the current and calibrate it in the code ;)

تحية طيبه هل ممكن المساعده بموضوع car mirror folding controller احتاج لدائرة تفصل الموتور اوتوماتيكيا بدون استخدام switch limit فقط بواسطه current sensing ولكم الشكر الجزيل
@EslamsLab
@EslamsLab 5 років тому
هتحتاج دايرة low side current sensing و هتاخد الخرج بتاعها على ترانزستور و توصل الترانزستور مكان السويتش مع مراعاة اتجاه التيار بس طبعا السويتش الميكانيكي العادى امان بشكل اكبر من الدايرة لأن الموتور كل مرة هيشتغل للحظة علشان الدايرة تحس بيه و توقفه

If we change the voltage value, is the current will measured correctly?
@EslamsLab
@EslamsLab 5 років тому
Yes because it depends on the difference between both ends on the resistor

well thats kind of a static measurement because you know the value of the RESISTOR is 8 ohms.. what if u dont know the load ohm? you have a system that you want to calculate its ampere drain.. you cant really do with that method can you?

Thanks a lot sir amazing work but i have doubt why you have used 1/200(.005)? and is it possible to measure directly with led? Waiting for your kind response
@EslamsLab
@EslamsLab 5 років тому
Hi peradeep I have used .005 because it depends on the resistor value " lower resistors gets lower resulting but can measure higher current " The other question is not clear for me :)

Hi To exchange data between your arduino and your phone you need just to connect your serial Bluetooth to arduino and use the same code Then download any app can view serial data from arduino
@EslamsLab
@EslamsLab 5 років тому
For any other modules you need to use the other modules code with serial print command to view the data
