Water Flow Sensor 1/2 inch YF-S201 | Liquid Flow Measurement Device

Description

YF-S201 water flow sensor is a commonly used device to measure the flow rate of water in various applications. Please note that there might be updates or changes to the product since then, and it’s always a good idea to refer to the latest documentation provided by the manufacturer or seller for the most accurate information. Here’s a general description of the YF-S201 water flow sensor based on my last knowledge update:

1. Type: The YF-S201 is a Hall effect water flow sensor. It typically consists of a plastic body with a turbine inside that rotates as water flows through it. The Hall effect sensor detects the rotation of the turbine and generates electrical pulses in proportion to the flow rate.
2. Flow Measurement: It is designed to measure the flow rate of water, usually in liters per minute (L/min) or gallons per minute (GPM), depending on the specific model.
3. Output Signal: The sensor typically provides a digital pulse output, with each pulse representing a specific volume of water passing through the sensor. The signal is usually in the form of a square wave.
4. Connection: The sensor may have three wires for connection – power (VCC), ground (GND), and signal output. It’s essential to connect the sensor properly to the power supply and the monitoring system.
5. Accuracy: The accuracy of the YF-S201 sensor may vary, but it’s generally suitable for applications where precise flow rate measurements are not critical.
6. Applications: Common applications include water heaters, water purifiers, water dispensers, industrial equipment, and other systems where monitoring and controlling water flow is important.
7. Compatibility: The sensor is often compatible with microcontrollers such as Arduino and Raspberry Pi, making it popular among hobbyists and DIY enthusiasts for various water-related projects.
8. Material: The body of the sensor is typically made of durable plastic, and the turbine inside is usually made of materials resistant to corrosion.
9. Environmental Conditions: The sensor is usually designed to work within specific temperature and pressure ranges, so it’s essential to operate it within the specified conditions for accurate measurements.

Always refer to the datasheet or documentation provided by the manufacturer for the specific technical details, wiring diagrams, and usage guidelines for the YF-S201 water flow sensor model you have, as there may be variations between different versions or manufacturers.
