FYP II Week 2 - 3: LDR circiut (sensor)

LDR circuit already construct on breadboard

  Sensor circuit diagram

 Simulation on bright condition

 Simulation on dark condition

This circuit is using LDR(Light Dependent Resistor) as the sensor to sense the sensitivity on the sun radiance. In this project there 2 of this circuit needed to keep the solar panel on track to keep it 90 degrees face toward the sun. The input voltage of this sensor circuit is 6V.

The component of this circuit is :-

• 330 ohm-2
• 1k ohm-1
• BC547-2
• 1k ohm(variable resistor)-1
• LDR sensor-1
