XH-M131 LIGHT CONTROL SWITCH PHOTORESISTOR RELAY MODULE-5V

The XH-M131 LDR Relay Module is a compact and easy-to-use module that can be used to control a load based on the intensity of ambient light. It utilizes a photoresistor to detect the ambient light level and triggers a relay when the light intensity falls below a certain threshold. This makes the module ideal for applications such as automatic streetlights, nightlights, and security systems.

This LDR Relay Module is a versatile and easy-to-use module that can be used for a wide variety of applications. With its compact size, wide operating voltage range, and high load capacity, this module is a valuable addition to any electronics hobbyist’s toolbox.
