15 Feet Automatic Sensor Door

Sensors in automatic doors detect movement, pressure, or infrared pictures, causing the doors to open or shut. The doors will open as soon as pressure or movement is sensed, and they will shut when the detectors can no longer sense anything.Nowadays, most automatic doors operate with motion-detecting sensors. The majority of motion detectors use either microwave pulses or passive infrared (PIR) sensors to detect movement.The sensors detect any change in pressure or weight which triggers the further mechanism and opens the door. As long as the weight is placed over the sensors, the doors will remain open. This eliminates any chance of doors closing on an individual.
