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.  

電阻元件的電阻值大小一般與溫度，材料，長度，還有橫截面積有關，衡量電阻受溫度影響大小的物理量是溫度系數，其定義為溫度每升高1℃時電阻值發生變化的百分數。電阻的主要物理特征是變電能為熱能，也可說它是一個耗能元件，電流經過它就產生內能。電阻在電路中通常起分壓、分流的作用。對信號來說，交流與直流信號都可以通過電阻。

Precision resistors is of low tolerance and low temperature coefficient, Thunder Precision Resistors makes ultra precision resistors and ultra precision resistor networks.
