The Digital Day / Night Fan Speed Controller (BETA-2) offers an efficient solution to control variable-speed fans based on real-time temperature readings. With its built-in photocell sensor, the BETA-2 distinguishes between day and night, adjusting fan performance accordingly. This smart controller ramps up fan speed to enhance cooling or slows it down to conserve energy—delivering a cost-effective method of heat management in enclosed environments such as grow rooms or greenhouses.
