I came across the circuit design and a lot of good circuit examples of DC current sensing and advice on the linear technologies website [http://www.linear.com/ad/current_sense.jsp here]. The circuit above is half of the battery current monitor circuit which can be found in their [http://www.linear.com/ad/08-dc.pdf DC pdf]. Half is only needed since for measuring current flowing from a micro-generator to a load the current only flows in one direction. The battery monitoring circuit measures current flowing in two directions: current flowing to the battery - charging and current flowing from the battery discharging. I have built the battery monitor circuit so that I can use it for both applications if I need to and the added expense is small. When measuring the total output of the turbine only half of the circuit is needed. | I came across the circuit design and a lot of good circuit examples of DC current sensing and advice on the linear technologies website [http://www.linear.com/ad/current_sense.jsp here].
