While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.

This Design Idea implements a remote sensor preamp (e.g., for a piezoelectric transducer) which transfers both signal and power over a single wire pair or coax. R6 provides a matching load to the ...

The Type LM35 temperature sensor from National Semiconductor is very popular for two reasons: it produces an output voltage that is directly proportional to the measured temperature in degrees Celsius ...

Allegro MicroSystems, LLC introduces a new Hall-effect based integrated circuit (IC) that provides a user-friendly solution for true zero-speed digital ring magnet and gear tooth sensing in two-wire ...

This application is as useful today as it was when I described it in the Oct. 1, 1996 issue (see "Two Wires Carry Power And Data"). The deployment of sensors has increased significantly, resulting in ...
