Make this Simple Humidity Controller Circuit using IC 741

Today I am going to explain a simple humidity controller circuit which works in a very interesting way.

Instead of using expensive humidity sensors, this circuit detects humidity by observing the transparency of a glass surface. When moisture forms on the glass due to high humidity, the light reaching an LDR changes, and that change is used to automatically switch a water sprinkler or any external load.

The circuit is simple, low-cost, and very reliable for basic humidity-based automation projects.
