Abstract
The invention discloses a water card alarm, comprising a main controller, a flow rate sensor, a water outlet switch, an alarm and a water card holder. The flow rate sensor, the water outlet switch, the alarm and the water holder are respectively connected with the main controller. When a water card is still in the water card holder after the water outlet switch is closed, the main controller outputs a signal and the alarm gives an alarm. The water card alarm has simple structure and can remind users of pulling up the water card in time, which not only can avoid economic loss of the water card users, but also brings more convenience to the life of the water card users; meanwhile, the water card alarm has low cost and easy popularization.
Description
Technical field
