I have never seen an LED circuit that is dedicated to indicating the presence of low values of current flow. This simple LED current sensor measures a low voltage drop across a sensing (shunt) ...

First of all, note that the circuit as it stands is only really intended to show how a basic current sensor module can be built and act ... Regulated 5VDC is required to power up the finished module.

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two ... generated by the sensor circuit can’t be detected ...

The basic setup for his use case ... the twisted pair is a power supply and decoder circuit, which sends 9 volts up the line to power the PIC sensor. The decoder is based on a CD4538 dual ...

Allegro Microsystems has introduced isolated differential current sensor ICs based ... fields from near-by circuit conductors and motors. Islation is UL60950-1 (ed. 2) certified with 4.8kVrms ...
