A drop from Smart Cooler in air temperature entering the air conditioning or air chilling unit dramatically increase the cooling capacity of the cooling system. Water level indicator is a system that relays information back to control panel to indicates whether a body of water has a high or low water level. Some water level indicators use a combination of probe sensors or float switches to sense water levels. Smart Cooler has frequent refilling of water. It has circuit to refill water automatically in an air-cooler tank when the water drops below a predetermined level. In case any absence in room the smart cooler automatically turn off which help in saving the electricity.
