Light to Voltage Converter (CB1332E)

     In this circuit, unlike the previous (CB1331E) the increase of the light in the sensor, makes the output voltage to decrease. The potentiometer can be 100 k and the capacitor determines the inertia of the circuit and can have values between 1 uF and 100 uF. The transistor may be the BC548.
