• Detects distance for security and intruder presence.

• Magnetic Field sensor

• Measures the temperature of an object or environment via direct contact or surroundings.

• Infra-red sensor

• Measures how close an object is by emitting and receiving electromagnetic radiation.

• Temperature sensor

• Measures ambient light; used in automatic systems to control lighting, like streetlights.

• Light sensor

• Measures the presence of a magnetic field emitted by nearby objects.
