🌞 LDR Sensor Module – Light Detection Module by ekastore
Add light sensitivity to your electronic projects with the LDR Sensor Module by ekastore. Based on a photoresistor (LDR – Light Dependent Resistor), this module detects changes in ambient light and outputs both analog and digital signals, making it ideal for automation, smart lighting, and daylight-triggered systems.
Whether you’re building a light-activated switch, streetlight controller, or an Arduino-based light meter, this compact module makes integrating light detection into your circuits simple and effective.
