The OSC05-RMW occupancy sensor is an infrared and ultrasonic sensor.
The maximum detection distance is 42m2. The sensor itself has a switch to delay the sensor's operation and a switch to adjust the detection distance.

Infrared and ultrasonic sensor
Maximum detection distance of 42m2
Switches to delay the sensor's operation and adjust the detection distance for custom operation
Simple ceiling mount installation with a small size

This sensor is connected to the DI input of a relay module or lighting control panel to operate the corresponding relays.
To prevent frequent operation of the sensor, there is a switch to set the delay time on the sensor, delaying the operation for up to 30 minutes. This means that the relay will not turn off immediately when a person leaves the detection range, but will wait until the set time has passed before turning off.

Passive Infrared.
