Comparators LM393 chip, stable.
With 4 fixed bolt holes, easy to install.
With power indicator light, Relay indicator.
Using strength photoresistor light sensing, comes 5V relay, direct load control.
With potentiometer sensitivity adjustment, by adjusting the potentiometer, set the starting relay threshold, when the brightness is greater than the threshold, module and relay, brightness is less than this threshold value, the relay is released,Connected to the common terminal is normally open during the day to control the switches, connectors, normally closed to the common terminal of the switch is to control the evening.
