描述
G3&4″ Water Flow Sensor 6分 G3/4 水流量傳感器
G3&4″ Water Flow Sensor 6分 G3/4 水流量傳感器 主要由塑膠閥體 、水流轉子元件和霍爾感測器組成。它裝在熱水器進水端，用於檢測進水流量，當水通過水流轉子元件時，磁性轉子轉動並且轉速隨著流量變化而變化，霍爾感測器輸出相應脈衝信號，回饋給控制器，由控制器判斷水流量的大小，進行調控。

G3&4″ Water Flow Sensor
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 hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.
We have a comprehensive line of water flow sensors in different diameters. Check them out to find the one that meets your need most.

Hardware Installation
You will need Seeeduino / Arduino ,Water Flow Sensor,10K resistor,a breadboard and some jumper wires.
Wiring up the Water Flow Sensor is pretty simple. There are 3 wires: Black, Red, and Yellow. Black to the Seeeduino’s ground pin Red to Seeeduino’s 5v pin The yellow wire will need to be connected to a 10k pull up resistor.and then to pin 2 on the Seeeduino.
Here is a fritzing diagram I made to show you how to wire it all up.
Once you have it wired up you will need to upload the following code to your Seeeduino. Once it is uploaded and you have some fluid flowing through the Water Flow Sensor, you can open the serial monitor and it will display the flow rate, refreshing every second.
