TL071 JFET Light Sensor Circuit

This is a design circuit for light sensing circuit. Here is the schematic figure circuit;


Above picture shows how to use an ordinary LED as a light sensor. It makes use of the photovoltaic voltage developed across the LED when it is exposed to light. Component: TL071 IC, Resistor, Diode.
