Easy LED Photo Sensor Circuit With LM1458

Posted on Feb 6, 2014

This circuit is used J-FET for recieve signal to buffer from LED, About Output voltage, We used IC 1458 or LM1458, while in the dark is about 7 volts and the drop about 2 volts in full sun. The LED voltage buffered by a junction FET transistor and then applied to the input of an operational inverting amplifier with a gain of about 20 minutes. This

is a variation of about 5 volts of darkness and light. You can adjust the 100K potentiometer to set the range of output voltage.
