Your Light Sensor is designed to activate your door over a gradual light change so that it does not open the door in a lightning storm or in car headlights, for example. The sensor takes a regular average reading to account for this. Covering the Light Sensor with your hand will activate it. Also, please note that if your Run-Chicken Automatic Coop Door is positioned near a floodlight or streetlight, this may affect the sensor, so you may need to orient it in a position with less ambient light.
