Hotel room hand sanitizer dynamic management device

Provided is a hotel room hand sanitizer dynamic management device. A liquid level sensor [2] and a remote transmission module [3] are arranged on each hand sanitizer bottle [1] of a hotel. Each liquid level sensor [2] continuously monitors the remaining amount of hand sanitizer in the corresponding hand sanitizer bottle [1]. When the hand sanitizer is used up, the remote transmission modules [3] send prompt information to a remote terminal management device [4] to remind relevant personnel to correspondingly feed hand sanitizer. Each liquid level sensor [2] is usually arranged at one side of the bottom of the corresponding hand sanitizer bottle [1]. The liquid level sensors [2] and the remote transmission modules [3] are powered by direct-current batteries. When the batteries are running out, a prompt message can be sent to the remote terminal management device [4]. The liquid level sensors [2] and the remote transmission modules [3] are waterproof. The remaining amount of hand sanitizer can be monitored in real time, and a prompt can be issued in time to ensure continuous supply of hand sanitizer.
