Several engineering communities provide custom sensor libraries for Proteus. You can find "exclusive" sensor packs, which often include the
Obtain the .IDX and .LIB files for the YFS201 sensor (usually packaged together).
: Move the .LIB and .IDX files into the Library folder of your Proteus installation (usually located in C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY ). yfs201 proteus library exclusive
The firmware must calculate incoming pulse frequencies over a defined time window to determine the current flow rate.
The sensor contains a plastic valve body, a water rotor, and a magnetic Hall-effect sensor. When water flows through the rotor, the rotor rolls. The firmware must calculate incoming pulse frequencies over
The following production-ready Arduino sketch handles external interrupts, tracks timing, and calculates both immediate flow rates and cumulative volume totals.
: The relationship between pulse frequency ( ) in Hz and the volumetric flow rate ( ) in Liters per minute ( L/minL/min ) is expressed as: F=7.5×Qcap F equals 7.5 cross cap Q a water rotor
, because the default installation of Proteus Design Suite does not include a native model for this component. The
The schematic capture graphic looks exactly like the 3-pin sensor module, making your circuit designs clean and professional.
