- Light Sensors: Automatic streetlights (photoresistors + Ohm's Law in circuits)
- Temperature Sensors: Smart thermostats (Nest – heat transfer principles)
- Pressure Sensors: Elevator floor detection (Pascal's Law + force calculations)
- Switches: Touchless faucets (capacitive sensing – electric fields)
Design Principles:
- Permanent: Smart home systems (integrated sensor networks)
- Temporary: Weather balloons (pressure/temp sensors)
- Situational: Motion-activated lights (kinematics)
