Abstract
The invention provides a bathroom exhaust fan control system. A control unit sends a first signal to a bathroom exhaust fan to turn on the bathroom exhaust fan, and sends a second signal to the bathroom exhaust fan to turn off the same. A heater water outlet measurement unit sends a third signal to the control unit when continuously sensing that water velocity is higher than preset water velocity within first preset wait time; the heater water outlet measurement unit sends a fourth signal to the control unit when continuously sensing that the water velocity is lower than the preset water velocity within second preset wait time. The control unit sends the first signal to the bathroom exhaust fan to turn on the same when receiving the third signal from the heater water outlet measurement unit; the control unit sends the second signal to the bathroom exhaust fan to turn off the same when receiving the fourth signal from the heater water outlet measurement unit.
