The SmartExhaust™ is a bathroom fan, light switch, delay timer, and ventilation controller. By using a microprocessor to monitor and control fan operation, a precise amount of ventilation can be provided. There are two settings on the switch - ventilation and delay. Ventilation is the minutes per hour that the user wants the fan to operate. Delay is the number of minutes the user wants the fan to run after the bathroom light has been turned off. The delay time provides additional run time of the fan to complete ventilating the bathroom after use. When a person enters the bathroom and turns on the light, the fan is also energized. After the person leaves the bathroom and turns the light out, the fan continues to run for the set delay time. The microprocessor monitors manual operation time and delay time and subtracts it from the set hourly ventilation time.
