Using a flow meter, he measures how much water leaves the tank. Assuming that you know it was once full, you can deduce how much water is left. Using a YF-S201 flowmeter on a Raspberry Pi, the ...

This diagram shows the hardware layout of the system. Two flow sensors are used because we have a low output well, ... The water flow sensor I used is an H2OPro HA-1045 Hall Effect Sensor. The main ...

Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The ...

Fig. 1: Circuit diagram for Motion Activated Tap Water Flow Circuit. Before understanding the working of the project, let us understand the workings of the PIR motion sensor, which is the heart of ...

E ver wondered how a water metre works? Well,a water meter is mechanical devices that measures the flow of water entering your house. A meter is read monthly. By the way, different types of water ...

This paper presents an application based on a hot wire anemometric sensor in MEMS technology in the field of water flow monitoring. New generations of MEMS sensors feature remarkable savings in area, ...
