5. INSTALLATION (HARDWARE)
The hardware installation is divided into two parts. The first part is sensor board. Following
figure shows example of wiring from sensor board to a microcontroller.
Simply connect the “+5” and “Gnd” to 5V supply, further connect the “Sig” pin to
microcontroller input pin. Normally, the “Sig” will be connected to Counter/Clock/Encoder
input for automatic counting purpose.
Second portion of hardware installation is the slotted disc. This disc should be mounted to
motor shaft or gear output as shown in following figure.
