Automatic electronic ON/OFF control device for all types of electrical/electromechanical/electronic applications

摘要

Electronic device with a single passive infrared sensor mounted on a movable, motor-driven, orientable support whose function is to scan the area where it is installed for the purpose of holding the actuator relay ON solely in the presence of persons, from the time they first enter, even if they are not moving inside the said area. The passive infrared sensor mounted on the device and oriented towards the entrance to the area will, when the first person enters, set the control logic that activates the movement of the sensor and the actuator relay to ON. The system will remain active for as long as there are people present and when the last person has left it will revert to the OFF status in real time. The said device permits a saving of electrical power with all the advantages of automation. IMAGE
