20PCS 5mm Photoresistor LDR CDS Light-Dependent Resistor Sensor (GL5516) - For Arduino & Electronics

Hey makers and electronics tinkerers!

Need to add light-sensing capabilities to your project?

This bulk pack gives you 20 pieces of GL5516 photoresistors.

These are 5mm CDS cells, also known as light-dependent resistors (LDRs).

Their resistance changes based on how much light hits them—perfect for things like automatic night lights, light meters, Arduino projects, or any circuit that needs to react to ambient light.

They're brand new and ready to solder into your next creation.

Whether you're a hobbyist, a student, or a pro, having a bunch of these handy sensors in your parts bin is always a good idea.

Grab the 20-pack and never be caught without one!
