The sensors will power on lights at night or during the day, and an adjustable dial allows your lights to remain on for up to 2 minutes (full clockwise turn to 10 equals 2 minutes, and a full counterclockwise turn to 1 equals 45 seconds). The single-channel sensor has a 30-Amp maximum load and operates within a 12-24 VDC range. Price for each.
