The Photoswitch will engage a relay when light level drops below a certain level. This module is great for turning on lighting at night and back off again when the morning sun returns. Detection and brightness detection is adjusted via potentiometer brightness control (Sensitivity Adjustment).

When the circuit is triggered, the output will activate the onboard relay which can directly control AC or DC loads, with a maximum load capacity of AC 0V--250V/10A, DC 0V--30V/10A

Operating Voltage: 12V DC
Mounting: 4 fixed holes for easy installation
Module Dimensions: 5cm x 2.7cm x 2cm
Sensor: Photosensitive resistance module (Light Dependent Resistor – LDR) is sensitive to ambient light
