If you can recommend on equipment it will be great.
Equipment for what? Measuring resistance? The Arduino can't. It measures voltages. Sending the data? How much data? How often? How far? In what kind of environment? With what acceptable failure rate? Do you need bi-directional communication? What is your budget?
I need 6.5 digits
every 0.1seconds at least
not familiar with failure rate.
Budget is less problem BUT the transmitter package should be as small as it can.
That means 6 and half characters? How can you have half a character?If that means 6 characters before the decimal point and 5 after the decimal point, dream on. There is no way you are reading the accuracy of a resistor to 0.00001 ohms, no matter how you try. Perhaps you ought to observe the tolerance of the resistors you are trying measure.
What sort of wireless are you using? I am open for suggestions range is 50cm I need to read resistance in the range of 100MOhms with digits as : 100.000 +-0.5 OhmsThe size of the transmitter should be as low as it can. I am using 1V to operate the resistor.data rate should be reading every 0.1sec (if it can be less than that, it will be great)Accuracy and failure rate are very important.Budget for this project is less problem.I need to read only one resistor but may buy 2 or more setups.Thanks.Sagi
