Actually, I am trying to build a current monitor for a wireless sensor network. I am going to use a current sense resistor as the current will pass through the resistor. By measuring the value of the voltage, the current value can be calculated.

My application is very sensitive as the current that will be measured is in the range of mA, 30 mA maximum.

When it came to buying the resistors I got confused. I found a type of resistor called 'precision resistor' that has a very small error, and another one called 'current sense resistor'. I wasn’t sure what were the differences between these to types of resistors, not until one day I reached out to Thunder-precision resistor, their customer service department presented a clear explanation to me.
