    Abstract: The present invention provides a door closer control system that includes a door closer having a rack and pinion mechanism connected to a pair of shafts with different length and a pair of springs. The shorter shaft is attached to the pinion of the door closer and will rotate in conjunction with the pinion as the door opens or closes. The shafts have correspondent gears connected to the shafts. The rotation of the first gear will be meshing with the second gear on the second shaft. Electronic sensors are placed on both sides of the door to detect a presence of an object and are activated by the movement of the solenoids. The movement of the solenoids cause a set of springs in the system to engage and disengage from a link to allow free motion of the door.
