Keyes K853518 Photosensitive Sensor For Arduino - Pack Of 2 Light Sensing Modules

About This Product

Calling all Arduino enthusiasts and electronics hobbyists! These Keyes K853518 photosensitive sensors are perfect for adding light-sensing capabilities to your projects without breaking the bank. You get two sensors in the pack, which is awesome because you can use one for your current project and have a spare for the next idea, or use both in more complex setups. The high sensitivity means they can detect even subtle changes in ambient light, making them perfect for automatic night lights, weather stations, smart home systems, or any project where you need to respond to lighting conditions. The module operates on 3V to 5.5V DC power, which works perfectly with most Arduino boards and other microcontroller systems. The analog output gives you precise light level readings rather than just on/off detection, allowing for much more sophisticated projects. I love that they include a 20cm output cable with single pin-headers already attached - makes connecting to your breadboard or Arduino so much easier. The 3mm mounting holes mean you can permanently install these in your projects without worrying about them coming loose. Whether you're a beginner just getting into electronics or an experienced maker working on advanced projects, these light sensors are reliable, easy to use, and deliver consistent performance. They're one of those basic components that open up so many creative possibilities for automated systems and interactive projects.
