In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present application.
At present, shared facilities are common, and various shared offices, shared buildings and the like are also increased. In order to make the management organization of these shared facilities grasp the resource usage of each tenant, a data recording scheme of "wind, fire, water, electricity and coal" of the device is receiving much attention. The strong and weak electricity systems in many sharing devices have employed smart relays and cloud-based customer registration systems to record and control electricity usage for each tenant. However, the current water consumption detection mode still needs to be based on the display data of each house water meter, and a water flow measuring device taking a water tap as a unit does not exist, so that the water consumption of each tenant in a shared facility cannot be detected in a subdivided mode.
The traditional water flow measuring methods are various and comprise a buoy method, a color tracing method, a salt solution tracing method, a flow method, an electrolyte pulse method and the like. However, these measurement methods require manual visual inspection and data input, and cannot be directly used in an automated scheme. Moreover, these devices are expensive, large and not suitable for use in a typical home or office setting.
Based on this, the water flow detection device and the system that this application embodiment provided can solve the lower technical problem of present water consumption detection mode fineness that exists among the prior art.
For the convenience of understanding the present embodiment, a water flow detecting device and a water flow detecting system disclosed in the embodiments of the present application will be described in detail first.

Once water passes through this water flow detection device, the water flow will cause the water flow rotor assembly of the hall water flow sensor to rotate. Because the inside of the rotor is provided with the ferromagnetic material, the rotor can be detected by the Hall sensor when rotating. Each pulse signal represents the rotation of the rotor so that if there is an advanced calibration, the pulse signal can be converted to the amount of water passing through the faucet.
In this embodiment, the hall water flow sensor is used to detect a water flow derived pulse signal. Specifically, as shown in fig. 3, the hall water flow sensor includes: the Digital-to-Analog Converter (ADC), Enable (EN) signal module, General-purpose input/output (GPIO), power supply voltage module (Vcc), RESET circuit (RESET, RST), data transmission module (Transmit, TXD), data reception module (Receive, RXD), and wire Ground (GND) module.
