Can this product be used to turn off electrical power? - for example: I have a worker working near a hazardous piece of equipment - he gets to close to equipment and the proximity warning system cuts power and turns off machinery.
Yes. The BodyGuard proximity detection and warning system has a switched output that is activated when an object (in this case a person wearing a "Tag") id detected within the user adjustable proximity detection zone. The output could be used to control a relay, which in turn is used to control your electrical switching.
