Description: DIY : Learn How to make a dark sensor using LDR (Light Dependent Resistor) and Operational amplifier (op-amp LM358). This circuit can be use in street light. Low light automatically trigger the output high. LDR is a light-controlled variable resistor. The resistance of a photo-resistor decreases with increasing incident light intensity.
