💡 Light Up Your Projects with EBOOT's Photoresistors!
The EBOOT 30 Pieces Photoresistor set includes 5 mm GM5539 resistors, designed for a maximum voltage of 150V DC and a wattage of 100 mW. With a spectral peak of 540 nm and light resistance ranging from 50-100 Kohm, these resistors are perfect for a variety of DIY and hand-working projects, operating efficiently in temperatures from -30°C to +70°C.

Works great with an ESP32 controller.
I heat my well house in the winter with a 60 watt light bulb. I've been using an ESP32 in the well house to transmit the temperature to my network. I've just added this photoresistor to monitor the status of the light bulb. If the light should be on and the photo resistor doesn't detect the light, it will send me a text message.

Work Great!
They work great. I messed the first one up when my soldering iron was too hot, but I learned my lesson and lowered the temperature on the second one. Good that this is a big bag, so I can mess up 29 more times! They work great on the breadboard too. For my application with Arduino Nano, each 22K resistor added between 80-100 points to the analog input signal (1023 max). So I had to add at least 6 resistors, to get a 1.0 in the digital port. I will add a 250K variable resistor (potentiometer) to my board next time to make adjustments easier.

Cheap price, cheap quality
I was attempting to use these photoresistors in a project I was attempting to complete. The project consisted of using the photoresistors to automatically face my small solar panel towards the sun. The photoresistor’s tolerance fluctuates wildly between each resistor. I had to sit down and manually check for matching ambient resistances to use for my project. However, I’m not really disappointed as they were extremely cheap and at the end of the day I was able to use them in the project. I just had to do a little bit of extra work.
