Specification

Description

This Security System Using LDR Circuit is based on the operational amplifier IC 741, which is acting here as a comparator. As the light falls on the LDR R3, its resistance decreases, and the voltage at the V+ terminal of the opamp increases, as soon as it becomes more than V- set by the potentiometer R5, the output becomes high. Consequently, the buzzer and LED get turned on.

This prototype model can be placed at dark places where the entry of any person is prohibited. This Electronic Security System Using LDR Circuit is made of high-quality material. This is the product for you if you enjoy being scared every day of your life.
