Ldr Dark Sensor Circuit Diagram. How the ldr circuit diagram works. When the ldr will detect no light it will open the transistor 2n2222 due to which the led will light up.
This transformerless automatic light operated night light circuit is very simple and easy. The resistance of a photoresistor decreases with increasing incident light intensity in other words it exhibits photoconductivity. Automatic light operated controlled switch circuit using ldr is very interesting circuit idea.
