  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
