App Concept
PanelGuard Pro
PanelGuard Pro is a portable, battery-powered device that electricians place against the back of an electrical panel to detect and warn of nearby fasteners or drilling from the opposite side. It uses capacitive sensing or ultrasonic technology to alert the user with lights and sound before a screw breaks through, preventing damage, shock, and fire hazards.
Key Features
- Real-time detection of screws or drills approaching from the opposite side of the wall
- Adjustable sensitivity to ignore standard drywall and studs
- Audible and visual alarm with different tones for proximity levels
- Magnetic mounting panel that clings to the back of metal electrical panels
- Self-calibrating to different wall thicknesses and materials
Target Users: Electricians and general contractors working on multi-unit residential buildings where electrical panels are back-to-back with bathrooms or other rooms
Revenue Model: $199 one-time hardware sale with optional $9.99/mo subscription for firmware updates and data logging
