El escenario
Autonomous east-west solar tracker that compares two light-dependent resistor signals to position a PV panel toward the sun.
Qué hay en este dibujo
Lee las decisiones que hay detrás.
01
Use two LDR voltage dividers as light sensors
02
Use a PLC to compare sensor signals and drive relay coils
03
Use an SPDT relay H-bridge to reverse the DC gear motor
When a maintainable, relay-isolated solar tracking control loop centered on an industrial PLC is required.
