How to Get Good and Stable Long Term Performance from this IC: The power supply of this circuit is also 9V. Now the LED will become activated when the level or darkness on the surface of the LDR will reach at the preset level set by the 120K variable resistor in the circuit. The operating voltage of the is 9V DC.Īs in the above circuit the lm741 is also used in this dark sensor circuit in astable multivibrator mode but this time, for detecting darkness the middle pin of the variable resistor is connected with pin three / non inverting input of the IC. The LED will become activate when the light level on the LDR will reach the preset level set by the 120K variable resistor. The circuit is using an LDR sensor to sense light. the 120K variable resistor is used to adjust the sensitivity or activation point of the LED. This light sensor circuit shown below is using LM741 IC as a multivibrator in the circuit. This first circuit is a light sensor and the second is dark sensor circuit. There are two circuits show below using the LM741 IC. Replacement / Equivalent / Other Part Numbers:
