Robokart Robokart Water Flow Sensor Electronic Components Electronic Hobby Kit

1) You Just Need To Connect To Arduino Interrupt Pin 2, And Can Measure The Number Of Pwm Pulse/Interrupt Per Unit Of Time. The Water Flow Would Be Directly Proportional To The Number Of Measured Pulses. 2)Water Flow Sensor Can Be Used To Measure The Flow Of Liquids, I.E. The Consumption Of Liquids In Industrial Or Domestic Usage. For Example You Can Make A Robotic Cocktail Dispensing Machine, And Can Use This Sensors To Accurately Measure Components Like Soda, Water, Etc. 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. Connection Details: Red Wire Is +5v Black Wire Is Gnd White Wire Is Pwm Signal Output Description: Lowest Rated Working Voltage: Dc4.5 5v-24v Maximum Operating Current: 15 Ma (Dc: 5v) Working Voltage Range: Dc 5~18v Load Capacity: ? 10 Ma (Dc 5v) Temperature: ? 80 ?
