Das Szenario
Autonomous east-west solar tracker that compares two light-dependent resistor signals to position a PV panel toward the sun.
Was diese Zeichnung zeigt
Die dahinterstehenden Entscheidungen verstehen.
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.
