YF-S201 1/2″ Water Movement Sensor
This sensor sits in line with your water line and contains a pinwheel sensor to measure how much liquid has moved through it. There’s an integrated magnetic hall effect sensor that outputs an electrical pulse with every revolution. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.
The sensor comes with three wires: red (5-24VDC power), black (ground) and yellow (Hall effect pulse output). By counting the pulses from the output of the sensor, you can easily calculate water flow. Each pulse is approximately 2.25 milliliters. Note this isn’t a precision sensor, and the pulse rate does vary a bit depending on the flow rate, fluid pressure and sensor orientation. It will need careful calibration if better than 10% precision is required. However, its great for basic measurement tasks!
The pulse signal is a simple square wave so it is quite easy to log and convert into liters per minute using the following formula.
Pulse frequency (Hz) / 7.5 = flow rate in L/min.
Description
This sensor sits in step with your water line and comprises a pinwheel sensor to measure how a lot liquid has moved by way of it. There’s an built-in magnetic corridor impact sensor that outputs {an electrical} pulse with each revolution. The corridor impact sensor is sealed from the water pipe and permits the sensor to remain secure and dry.
The sensor comes with three wires: purple (5-24VDC energy), black (floor) and yellow (Corridor impact pulse output). By counting the pulses from the output of the sensor, you possibly can simply calculate water movement. Every pulse is roughly 2.25 milliliters. Notice this is not a precision sensor, and the heart beat price does fluctuate a bit relying on the movement price, fluid stress and sensor orientation. It would want cautious calibration if higher than 10% precision is required. Nonetheless, its nice for primary measurement duties!
The heartbeat sign is a straightforward sq. wave so it’s fairly simple to log and convert into liters per minute utilizing the next system.
Pulse frequency (Hz) / 7.5 = movement price in L/min
