🌟 I need a sensor that detects a mAmps current, just detect it, I don't need to measure it, the current is about 20mA, can you advice? Nice video, thank you 👍
Help needed..(Question) I have a 12v motor that works off a key fob opening and closing a sunroof..it has 2 buttons..one opens it one way completely..one opens it the other way..but nothing stops the power going to the motor unless you press the button again..even when motor is maxed out..unit keeps powering it until it blows something..i need some sort of current switch that will break the circuit momentarily when it bottoms out as killing the unit will stop the process..if i forget to press the fob to stop the motor opening it will fry motor..so essentially what i think i need is like a self resetting amp adjustable fuse..but not thermal as it will take too long to reset also..hey man..nice video..thanks for all the info..i have a nice little project on at the moment, would love your advice
Thanks glad you enjoyed it! Depending on your design whether you want to go noninvasive or invasive you should be able to get modules for these that have a relay embedded in so you will be able to turn the relay on or off depending on how much current you are drawing through the sensor. This is one solution of many, let me know if you'd like to have a chat to discuss further. Hope this helps!
@@WinterCircuits aw cool man thanks..i will check what amps its drawing in regular use and see what it spikes to when stalled out .thanks for quick response
If you need accuracy, as well simplicity I would suggest to use a shunt method current sensor, something such as the INA219, very simple to set up and reliable.
I watched your video it was very informative thank you! However I was wondering if you would be willing to help me on a project, I am building my own welder compressor generator and I'm trying to make an electronic auto throttle I have a good strong solenoid to shuttle the throttle back and forth with a return spring built-in so I only need 12 volts applied to a solenoid triggered by a current sensor my weld output range is between 75-200amps dc and for advice or design would I would be greatfull for, Thanks again for your time and your video!
Hi Alex, thanks for the feedback! I would be more than happy to help you along for your project. Let me know what's the best way to get in contact with you and we can discuss requirements and what we can do.
You look to know a lot so can you explain to me why am I getting 3.5 volt on the output of the op amp alway and if I add 1 millivolt to the no invertering I don’t get any gain from the ua471 and it data sheet said it’s gain is 1000 time and I don’t get any gain till I add 1 voltage the gain gos full the supply voltage why is this and I need it to sense current to control my load
Dam bro your videos are getting better, keep it up 👍
Thanks bro, really appreciate it!
Very informative video.

Can you tell me how use Zmct103c sensor to know if there is a possibility of a short circuit

@@emmettcoen No problem, let me know how you do and if I can help you out in any way.
why not using switches at the ends of the movements
Please help me, if I have a circuit that has an output of 50-200 mA, what sensors can I use to monitor this current?

Sir, i need current sensor which operate at 300v and 60A . And it should give alarm if its decrease than 10 A.
Great video. Thanx
Thanks for the info

You left out the most important category, cost!
Of course! I always say cost is the most important factor! Think it influences most of our designs!
