LDR Light-Dependent Resistor Module

About this product

Photoresistor module that detects ambient light level. Resistance drops with light intensity — useful for automatic lights, sun-tracking, dark-detection, or light-following robots. Provides both digital (threshold) and analog output options on most variants.

Ultrasonic, IR, temperature, humidity, motion, current, IMU and environmental sensors for prototyping, research and production.
