Is it possible to measure current using shunt resistor . Like used in clamp meter .
I am trying to build application to measure current 15A-20A @1000v.
is there a dc clamp meter that just "plugs" into arduino.. if so can someone point the way .. id like to look at it i may need a few. im trying to measure 200A@12VDC ... just not with a shunt. (becasue i dont know how to safly hook a shunt to an arduino yet... lol)
Dear all,I am trying to build application to measure current 15A-20A @1000v. I have build circuit with hall sensor and interface with arduino UNO using mux circuit.Now i am trying to build circuit on shunt basis .if anyone here can put suggestion to take care during building circuit will be appreciable.
Is it possible to measure current using shunt resistor . Like used in clamp meter . Its equivalent of string monitor in solar.
Measuring the drop across a series resistor in the ground leg of a power supply is perfectly do-able but not really advisable unless you have a means of sensing the voltage at the high side of the sense resistor to detect an open condition or all the electronics are TOTALLY isolated from everything AND I DO MEAN EVERYTHING else connected to that node.... IMO a lot of extra crap to emulate the inherent isolation provided by a hall effect device.... Safety is NEVER, NEVER a place to try to save a dollar or "Simplify" a design.You have been advised of how to do the task 'correctly' the obvious way, Twice... What is the underlying issue that keeps you asking about how to do something inherently VERY Dangerous.Were your engineering skills at the same level as your 'apparent' coding skills you would know this and not ask a useless question.1A @ 1KV is 1 KW... this is a NON TRIVIAL current and voltage and 'accidents or parts/construction failures are generally LETHAL to both the equipment and the operator.Doc
