inductive displacement, and eddy-current sensors? I asked a few friends and everyone had a pretty good idea, to varying degrees, but if you aren’t immersed in the topic the nomenclature can throw you ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module ... and use an external 5VDC power supply. If higher current loads are to be ...

The idea is simple enough: just place a INA219 current sensor between the power supply ... Of course in this case, [Mark] knew what the target Arduino Nano was doing because he wrote the code ...

These connect to an LX3302A inductive sensor IC, which reads the position of the copper slug inside the float. That simplifies the process greatly; [Mark] goes into great detail about the design ...

Packaging is 2.02 x 1.4mm WLP-8 or 8-pin μMAX. Intended uses include: battery stack monitors, current monitoring of inductive loads, PWM H-bridge motor current sensing (in-line, in-phase, winding) and ...
