Having a big block of hot to dump current into is a very useful thing to have if you’re testing batteries, power supplies, high power LEDs, electroplating, or any thing else that would normally ...

Some projects are both educational and useful. We believe that [Jasper’s] Arduino based electronic load is one of those project. [Jasper’s] electronic load can not only act as a constant current load, ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Though sometimes dubbed a load-dump sensor, it does not detect dumped loads. The term load dump refers to special circuitry protecting the sensor from high-voltage spikes in the vehicle wiring. The ...

The LS6506R is a pyroelectric infrared (PIR) sensor interface IC that is designed to drive a latching relay. However, the device can be used in a wall-switch configuration (no Neutral available) to ...

Panasonic. has filed a patent for a load sensor that aims to improve accuracy in measuring loads. The sensor includes a first and second base member, an electrically-conductive elastic body, an ...
