Hello to all, well i had a nice expirance of submitting the post, on the help of lcd interfacing.... well now i the problem is little bit different...
My problem is that i want to measure the Current (instead of Voltage) using ADC but the problem is that my ADC (or even all the ADCs) are capable of measuring the voltage (0-5v) but i want to measure the current ... so any one have idea how to measure the current...
Well i am working on project in which the current will be displayed on the Computer (in every instance of time) i might be using MAX232 with additional ADC with my 8051 MCU...(using UART) but the main problem is that how do i measure the current :-(
Well sir i have taken your advice and again i will insert the link ... ... well sorry everybody for duplicating the post....
"sorry everybody for duplicating the post...."
The duplication in itself is not the problem!
The real problem is the fact that you have ignored all those people who had already given you plenty of help.
Why have you abandoned the other thread?
You said you would research suggestions made there but, instead, you have just re-posted exactly the same text here without apparently having given it even a moment's thought! You didn't even update it to specify that you need to measure AC!
Well sir i am really searchig for it.... and yes i have only got the basic idea.. speacially i have founded one thing important... "Commercial Current Transformers..." ,,, and there is one more thing interusting... which is "STPM01" ,,, well according to its data sheet.... it can be used as standalone cureent measurer tool... :-)
This is the kind of problem that you solve by use of a multimeter, oscilloscope or similar and not too expensive components on the lab table before starting to wory too much about a uC.
However, there are quite a number of decisions to make before starting on a project. What are you going to measure. What current range. Maximum crest factor allowed. Required tolerance. Expected target price. Frequency range (actually quite connected to the crest factor), how to power the uC, any required isolation of uC from high voltages, requirements to support DC offset currents, ...
Without the above decisions, you can't really design a solution. On the other hand: Are you designing it for yourself or as a commercial product for a company? If it is the later, I would expect you to already have the required knowledge about how to measure, electrical safety, ...
