•Operating voltage: 5V to 12V
•Operating current: 15mA (5V)
•Operating Temperature: -25°C to 80°C
•Output Duty Cycle: 50% (±10%)
•YF-S201 Flow Rate Detection Range: 1 to 30L/min ±10%
•YF-S401 Flow Rate Detection Range: 0.3 to 6L/min ±10%
•Max water pressure: 1.75Mpa
•Connection interface: G1/2 thread (YF-S201) / 6mm tube (YF-2401)
•YF-S201 Pulse Frequency = 7.5 * Q(L/min) +/-2%
•YF-S401 Pulse Frequency = 5.5 * Q(L/min) -3 +/-2%
•This sensor is ideally suited to measuring liquid across it
•The sensor outputs a pulse that is relative to the speed at which the internal pinwheel is being turned
•This makes for a simple and effective method for monitoring watering/hydroponic systems as well as other fluid-based control systems
