ACS712 Current Sensor Tutorial with Arduino (Sensing DC and AC Current)

In this video, I am going to talk about the ACS712 sensor, how to measure DC and AC current with Arduino.

This is the first video I've seen showing acs712 noise through an graph... Thank you very much

Just minor correction:
6:18 If you are using the 30 amp type, you need to change the value in the code to 0.066 NOT 0.66.

Hello, in the video you suggested to not use ACS712 when the current is below 0.4A but INA219 or a CT sensor instead. In the video a picture of CT sensor was showed. Do you have a reference for it?

[ShilpaGireesh]

Hi, Could you recommend the above sensor for measuring a current less than 0.9mA from a board? My project is based on Arduino.

Thank you for sharing, sir. You made me happy too 🤗

[easy_d]

Using this we can check if AC power supply is on or off right? I mean if there is AC power loss we can detect it in the arduino. Exactly what i was looking for ! Thanks

Using a 240v to 12v adapter, can i short the + and - terminals on the left terminal block?

[mtrcurse]

Sir what sensor should i use for less then 0.4 amp sensitivity ?

[gpigna]

Thanks for this excellent video. Do you know what the maximum distance of the cable that connects the ACS to the Arduino board can be?... Thank you

[chandansaha]

It was a great videos. I want to measure current in microamps, what kind of circuit can i use.

[anthonybianue]

Can someone please explain to me how we are comfortable passing 30a in series through this tiny device with a tiny wire?

[ihtsarl]

Thank you for this video it will help me in my design.

[Krwawyyy]

Hi, do you have any idea how to implement this code in ESPHome? Please help me with this, I'm stuck

[Nayeong-ptgm]

Complation error: 'ACS712_30A' was not declared in this scope (What should I do?)

[PushprajPrajapati]

The code for measuring AC current is not functioning properly.

[talhatetik]

Can I use this sensor for ındustrıal electrical motor to monitoring current and consumption of the motor for predictive maintenece

[roopahyati]

thank you it really great help from your code...thank you..

Can the code be used in esp32 and when no load is connected adc value is 816
