Mini Photocell

The Mini Photocell from Sparkfun is an impressively compact light sensor, also known as a photodetector, photo resistor, CdS or photoconductive cell. This tiny device changes its resistance based on the amount of light it is exposed to, making it an excellent choice for ambient light triggers. For example, when the light in a room turns on, the photocell can be programmed to respond accordingly.

The Mini Photocell boasts several key features. It has a light resistance of approximately 1k Ohm and a dark resistance of around 10k Ohm. It can handle a maximum voltage of 150V and a maximum power of 100mW. The photocell measures just 2 x 4 x 5mm, with a 4mm gap between pins and a 31mm lead length.

The Mini Photocell is not only compact and versatile, but it's also easy to use. Sparkfun provides a range of resources to help you get started, including a datasheet, a hookup guide, and a Bildr tutorial. These documents provide detailed information about the photocell's specifications and how to use it, making it easy even for beginners to start experimenting with light-triggered responses.

One of the major benefits of the Mini Photocell is its adaptability. It can be used in a wide range of applications, from simple light triggers in a room to more complex projects involving ambient light sensing. Whether you're a hobbyist looking to add a new dimension to your projects or a professional seeking a reliable and compact light sensor, the Mini Photocell is a smart choice.

Another unique property of the Mini Photocell is its durability. Despite its small size, it can handle high voltage and power, ensuring reliable performance even in demanding conditions. With Sparkfun's Mini Photocell, you can bring your projects to life with the power of light.
