About sensors

Ultrasonic Wall Switch Occupancy Sensor is listed under Sensors — proximity, photoelectric, ultrasonic, hall and limit sensors. Sensors in this category detect the presence or absence of objects without physical contact, or by contact in the case of limit switches. Proximity sensors, including inductive and capacitive types, respond to metallic and non-metallic objects respectively, typically within short ranges (1-50mm).
