Solu20pcs Photoresistor LDR CDS 5mm Light-dependent Resistor Sensor Gl5516 Arduino//20 PCS Gl5516 Photoresistor LDR Photo Resistors Light-dependent// 20 PCS Photo Light Sensitive Resistor Photoresistor Gl5516

Extremely good. Measured dark ohms & were over 2 megaohms & light ohms were about 100 to 300 ohms (thats even better than their specs given which were about 18 to 20 kiloohms), but this is approximate as totally approximate measurement conditions. All in small bag, in perfect shape, arrived on time. Only bought them as trying to zero my account balance as don't have immediate use for item but I am glad I did. Highly recommend this item.

I used one of the photoresistors as soon as they arrived and it is working like a dream. Thank you for a very good product and fair price.

After watching a YouTube video on solar trackers, built a DIY sensor array using four of the Photoresistors and two old used Satellite Dish Actuator arms to build a 2D tracker for my solar panels. Works great.

Hey, they change resistance based on the intensity of the light falling on it. That's what we want. They all seem to be pretty close in resistance under a given light source and the price is great.

Resistance measurements are not LINEAR. Total darkness resistance samples are not near identical (33 to 120 Mohm). Partial darkness/light is also variable. Total sunlight measurements were also inconsistent - 800 to 25k ohms.

Great Product that works like it should. None of the pins were bent on arrival and all were tested and worked fine. Great quality at an affordable price!

Great price, and 100% worked correctly! Resistance in bright artificial light were all around 1.5K, and varying darkness over 20k. I suspect way over 20k, but it wasn't convenient to make it real dark.

These work as expected. The only trouble was the shipping package. these were insinde a box with several other items. Of course the box was crushed along the way and the photocells (unprotected) took most of the force. they were bent all to H. E. double hockey sticks. but i was able to use what i needed.

was pleased with this order thanks
