Description
YF-S201 Hall Effect Water Flow Meter / 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!
 
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) / 7.5 = flow rate in L/min.

Waterproof DS18B20 Digital Thermal Probe or Sensor

This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances!
