The OSC20U uses an Ultrasonic Sensor (US sensor) which works similar to radar or sonar. It is an active technology that sends and receives. It emits an inaudible high-frequency sound wave and evaluates the echo which is received back after bouncing around in the room. This allows the sensor to evaluate the whole room and can look over walls and obstructions to identify movement. The OSC20U provides a 360 degree coverage pattern of up to 1000 square feet. Sensitivity will increase as distance to the sensor is reduced. Sensitivity reduces further away from the sensor and may require a walking step to activate the sensor.
