Light Sensor Circuit Using Lm358. You just need to replace an ldr with phototransistor or photodiode the circuit simply works. The circuit is based on lm358 ic which is an op amp with an operating voltage range of 3v to 32v which is suitable to work with most micro controllers of logic level 5v or 3 3v.
This module can also be used for testing an ldr a phototransistor and a photodiode. Lm358 consists of two independent high gain frequency compensated operational amplifiers designed to operate from a single supply over a wide range of voltages. Some applications of this circuit are street light controlling home office light controlling day and night indicators etc.
