Switch circuit of pole light using LDR DIY Experiments Science Project Model STEM KIT Ready (Assembled), 100% Tested

Overview:
The Switch Circuit of Pole Light using LDR DIY Kit is designed for hobbyists, students, and educators looking to explore light-sensitive automation. Built around an LDR, comparator IC LM393, and relay, this kit demonstrates how to automate light control effectively. Pre-assembled and 100% tested, it ensures ease of use and reliable performance.

How It Works:
The LDR serves as the light sensor. In the absence of light, it triggers the LED to glow, simulating a streetlight’s automatic operation at night. The LM393 IC acts as a comparator to control the relay, switching the LED on and off based on light intensity.

Key Features:

• Uses readily available LDR and LM393 IC for cost efficiency.
• Simple yet effective circuit to automate light-based functions.
• Adjustable sensitivity using a variable resistor (R2).
• Operates on a standard 5V DC power supply.
• Durable components for long-term educational use.

Assembly Instructions:

• Refer to the included manual for step-by-step guidance.
• Use the provided PCB and carefully solder components in their respective positions.
