B&K Precision has introduced its SenseLite, an LED pocket flashlight/AC voltage detector. This battery-powered flashlight detects AC voltage when you shine it at an active socket, switch, or wire. The ...

Designed to illuminate the work area when tracing ac circuits in dark areas or behind equipment, the SenseLite is a battery-powered flashlight with a noncontact ac voltage detection circuit and a red ...

This is a CMOS IC (CD4033) based circuit which can be used to detect presence of AC mains voltage without any electrical contact with the conductor carrying AC current/voltage. Thus it can be used to ...

A low-cost chip that enables batteries in sensors to last longer, in some cases by over ten times, has been developed by engineers from the University of Bristol. Dr Bernard Stark and colleagues in ...

The growing number of plug-in electric cars, and also hybrids, as well as expanding solar market, leads to the topic of how emergency responders will be able to detect high DC voltage. One of the ...
