An LDR (Light Dependent Resistor) is a resistor that decreases its value as the luminosity increases.
This module with LDR and with an LM393 as a controller, generates its output at the DO terminal, being at a high level until the intensity of the light exceeds the established threshold and using the default value.
It also has 2 LED status indicators, one to indicate that it is working (On), and another to indicate the status of the output signal.
It also has a potentiometer that It will allow you to adjust the sensitivity.
Applications: Lighting control of rooms or spaces.
Vcc: 3.3 to 5 V
Output type: Digital in DO
Size: 32 x 14 x 7 mm
