A new sensor has been designed to replace mechanical float switches. The Leveltrak is an electronic non-floating sensor. It detects level without any moving parts. Using capacitative sensing ...

The NGFS Electric Field Sensor is an easy-to-install floating sensor with passive optics near line potential delivering high bandwidth and exceptional frequency response. Ideal for observing harmonics ...

Regular readers of Hackaday will know that the projects we feature are generally of the high-tech variety. Microcontrollers, 3D printed parts, embedded Linux, lots of wires, that sort of thing. But ...

A fleet of 100 floating robots took a trip down the Sacramento River on May 9, in a field test. The devices, equipped with GPS-enabled smartphones, demonstrated the next generation of water-monitoring ...

These cool looking little bots are part of a fleet of floating water sensors built by The Lagrangian Sensor Systems Laboratory (LSSL) at UC Berkeley, the Lawrence Berkeley National Laboratories (LBNL) ...

We are currently in the process of putting in a backyard pool. This is an in-ground gunite pool. I inquired about an auto-fill system from the pool builder but he talked me out of it. He explained ...
