💡 Automatic Night Light Circuit Using IRFZ44N & LDR – DIY Electronics Project!Want your light to automatically turn ON at night and OFF in the day? In this project, I’ll show you how to build a simple night light control system using an LDR sensor, a 100Ω resistor, and a powerful IRFZ44N MOSFET.
This circuit is ideal for smart lighting applications, garden lamps, street lights, or any low-power 12V system! It saves energy and works flawlessly without needing a microcontroller.
🔍 What You’ll Learn in This Video: ✔ How to use an LDR to detect light levels
✔ Working of MOSFET IRFZ44N in switching applications
✔ How the resistor and LDR work as a voltage divider
✔ Full step-by-step explanation of the auto light switch circuit
🧩 Components Used in This Project:
IRFZ44N N-Channel MOSFET – Switches the light based on input from LDR
LDR (Light Dependent Resistor) – Detects ambient light levels
100Ω Resistor – Controls gate current to the MOSFET
12V DC Power Supply – Powers the entire circuit
LED Light Module – Turns ON when it gets dark
