lets to see Automatic Op-amp night light circuit using IC-741. It is also very simple. As my feelings It has high sensitivity more than one,high accuracy.

An automatic dark sensor can be made using a PNP transistor(BC557).
In this case, LDR has been replaced with capacitor C1-0.01uF and resistor R3-1K has been replaced with L1 & VC1. In place of a LED, a Piezo Diaphragm has been kept. We just need to add inductor, capacitor and a piezo diaphragm to convert a dark detector to an AM radio.
Automatic Light detector using variable resistor A light detector senses light. As the light level increases and LDR meets the lowest threshold resistance, the circuit automatically turns on the LED D1. We can adjust the sensitivity using the preset VR1-10K. LESS RESISTANCE(VR1)-> LESS DARKNESS TO SWITCH OFF THE LED HIGH RESISTANCE(VR1)-> MORE DARKNESS TO SWITCH OFF THE LED
