The passive infrared sensor responds to moving heat sources such as people or vehicles. When the motion detector detects changes in thermal radiation within its detection range, it activates the connected devices, such as lighting, based on the set light value for a configurable duration. If the heat source leaves the detection area, the motion detector turns off the device after a preselected time of 3 seconds to 20 minutes. An additional feature is the short pulse, which can be adjusted using the integrated TIME potentiometer located under the sensor's cover ring. This allows, for example, stairwell lights in larger buildings to be automatically activated.
