Beautiful Tutorial if you could put a setting of the maximum electrical current beyond which disconnects a relay. It would be a beautiful implementation.
Thank you very much for your suggestion. 200A, 100A or even 50A needs huge relay to handle that type of current but possible. I will try to add the code into the current code.
Robojax Yes yes very good, either a mechanical relay or an SSR or a controlled SCR can be used to handle higher currents. It is important that in a row of the display the reference current set with the trimmer appears, in the second line the instantaneous electric current measured. as soon as the reference electric current set with the trimmer is exceeded the display will show the overcurrent writing and will go into lock then with a reset button the function will be restored. I await the changes based on my idea if it is possible. Thank you so much.
Until I have the components, I will not make any changes. Your request requires separate video. So I will take 30-50 days before I receive the components.
Hello, this is for AC and CD. Please see the updated video with library which meaks the code clean ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sB6EULTix2k.html I have mentioned int he video that is for AC and DC.
@@robojax yes thanks I noticed it! so I can connect the Hot line and Neutral of my AC 220 in input of ACS758 module? without any issue? thanks again for full of tutorials you made!
Hi, thank you for the video. I think that you have a unit mistake in your code. You have done : ``` float cutOff = FACTOR/cutOffLimit;// convert current cut off to mV ``` Maybe this was what you were trying to do (see below units used and cutOff) . If not, please help me to understand. ``` const float CURRENT_SENSOR_SENSITIVITY[] ={ 40.0,// for ACS758LCB-050B 60.0,// for ACS758LCB-050U 20.0,// for ACS758LCB-100B 40.0,// for ACS758LCB-100U 13.3,// for ACS758KCB-150B 16.7,// for ACS758KCB-150U 10.0,// for ACS758ECB-200B 20.0,// for ACS758ECB-200U }; // mV/A see datasheet const float MY_CURRENT_SENSOR_SENSITIVITY = CURRENT_SENSOR_SENSITIVITY[CURRENT_SENSOR_MODEL]/1000; // mV/A · (1V / 1000 mV) → V/A float cutOffLimit = 1.00; // Ampere float cutOff = MY_CURRENT_SENSOR_SENSITIVITY*cutOffLimit; // V/A · A → Volts float voltage; // Volts ```
Hi, I've put the link in the description to the latest video and code. I've written library for Allegro ACS current sensor which makes it simple and clean. here is the video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3C33DpcSwIw.html
Hi this is sensor is very expensive. If they supplier send me the sensor I can arrange making video for it. They can contact from robojax.com contact page
