Ceiling motion sensor OR-CR-235 ac 230v

Passive Infrared Sensor for Ceiling Mounting The sensor is designed to automatically control the switching on of building lighting (or other electrical devices) when motion is detected in the vicinity of its installation The heart of the device is a passive infrared sensor with a motion detection angle of about 360 degrees Motion detection is based on the principle of measuring the change in ambient temperature in a preset sector of the sensor's visibility, as a result of the movement of a person located there
After motion is detected by the PIR sensor, the lighting (or other electrical device controlled by the sensor) is automatically switched on and remains on as long as the motion sensor detects presence (motion) within the field of vision If no presence is detected within the specified (user-set) time, the lighting (or other electrical device) is automatically switched off
The sensor is additionally equipped with a special photo-optical sensor, which optionally allows to save energy by not switching on the lighting, e.g. during the day
