Abstract The low current measuring principle with the method of closed-loop feedback is described.The magnetoresistive transducer HMC1021, which is highly sensitive to magnetic field, is used for the collection module. The low power consumption and high-performance DSP chip--TMS320F2812 is used as the master controller in this system for low current accurate detecting and immediate processing.
