G1/2 Plastic Water Flow Sensor Turbine Hall Flowmeter for Arduino
It is turbine type water flow measuring sensor. When water flows through it£¬ it will output a number of pulses. By counting the pulses from the output of the sensor£¬ you can easily calculate water flow. Each pulse is approximately 3.33 milliliters. We have as example Arduino sketch that can be used to quickly test the sensor£¬ it will calculate the approximate flow of water in liters/hour. The pulse signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. Pulse frequency (Hz) = 5 * flow rate in L/min. Features: - Measurement flow range: 1~30 L/min - Working voltage: 4.7~15 VDC - Working current: ≤ 10 mA (DC 5V) - Working humidity: 35%~90%RH (no frost) - Working pressure: < 1.75Mpa - Working temperature: -25~+80¡æ - External thread: G1/2 (1/2") - Output connector: XH2.54MM-3P - Output leads: yellow (DATA)£¬ red (VCC)£¬ black (GND) - Lead length: 15cm - Application: water heaters£¬ credit card machines£¬ water vending machine£¬ water flow measurement device
