  How to make automatic street lights circuit using LDR

Use of LDRs

 

LDRs Use, in automatic safety lights, LDRs

(light-dependent resistors)

 are used to detect light levels.

 

When the light intensity increases, their resistance decreases

 in the dark and at low

light levels, an LDR's resistance is high and no current can pass through it. 

 

 

 

 

 

LDRs has Two pins Like Resistors
