The sensor does have some limits. It can only detect motion up to about 16.5 feet away. And while Philips will give you the option of reducing that — that is, only turning on lights when motion ...

Abstract: We present a new sensor for power monitoring that measures current flow in a circuit breaker without permanent modification of the breaker panel or the circuit breaker itself. The sensor ...

Improved signal conditioning electronics and new experimental results are presented for a sensor that measures current flow in a circuit breaker. A PIC microcontroller optimizes the phase reference ...
