Arduino Water Meter, Simple (4K)

This is a simple Hall Effect based water meter set up for the Arduino. It outputs to Serial Monitor Time operated, total liters, and instantaneous liters being delivered. The sensor is inline and uses an impeller with an embedded magnet. The magnet triggers a Hall effect switch sending a pulse at each revolution. There are 3 wires, red (power, 2-24 volts, but I've gotten it to work at 3 volts), black (ground) and yellow (Hall effect output). IMPORTANT: Depending on the amount of output in Serial.print, and how often you report, you may have to significantly increase your Serial.begin speed. HARDWARE / MATERIALS Arduino YF-S201 Water meter / sensor Jumpers Resistors / voltage divider if using 5v.  From the spec sheet: 16 Hz = 2 L/min = 120 L/hr 32.5 Hz = 4 L/min = 240 L/hr 49.3 Hz = 6 L/min = 360 L/hr 65.5 Hz = 8 L/min = 480 L/hr 82 Hz = 10 L/min = 600 L/hr etc. Max 30 L/min Frequency (Hz) = 7.5 * Flow rate (L/min) Pulses per Liter: 486 Model: YF-S201 Sensor Type: Hall effect Working Voltage: 3.5 to 24V DC (min tested voltage 3.3V) Max current draw: 15mA @ 5volts Output Type: 5volt TTL Working Flow Rate: 1 to 30 Liters/Minute Accuracy: ±10% Maximum water pressure: 2.0 MPa Operating Temperature: ≤80℃ Liquid Temperature: ≤120℃ Output duty cycle: 50% ±10% Output rise time: 0.04us Output fall time: 0.18us Min Durability: 300,000 cycles Cable length: 15cm 1/2" nominal pipe connections, 0.78" outer diameter, 1/2" of thread Size: 2.5" x 1.4" x 1.4" Notes: YOU NEED A VOLTAGE DIVIDER WHEN OPERATING ABOVE 3.3 VOLTS!!! WARNING: Warning: mis-wiring or mis-programming your Arduino or miswiring of accessories can ruin the Arduino and accessories. Data is from the manufacturer. Information/drawings offered as is. Use at your own risk. If you don't know, learn first or do not do it.
