Ever wanted to measure liquid flowing through a pipe / container? Wanted to create a control system based on the water flow rate or quantity ? For example while gardening, to measure the amount of water used to water your plants , to prevent wastage , etc. If yes, then this very easy DIY project is for you. Here, step by step instructions are given on how to measure water flow rate and quantity using an arduino flow rate sensor.
A flow sensor is a device for sensing the rate of fluid flow. Typically a flow sensor is the sensing element used in a flow meter, or flow logger, to record the flow of fluids.
Step 1: Components Requires
1. Arduino Uno
2. Flow Sensor
3. Connecting wires
4. LCD Display
5. 1K Ohm Resistor
Step 2: Circuit and Its Connections
Flow sensor Yellow Wire is output and it gives pulses in proportion with flow
Step 3: Programming the Arduino
Step 4: Testing and Results
1. Blow air or allow water flow through the sensor
2. Observe the reading on LCD or Serial Monitor
3. Readings get updated at every 1 Sec
