Photocells are basically a resistor that changes its resistive value (in ohms Ω) depending on how much light is shining onto the squiggly face. They are very low cost, easy to get in many sizes and specifications, but are very innacurate. Each photocell sensor will act a little differently than the other, even if they are from the same batch.
The Photocell-10 has a three blade plug-in locking electrical connection and it is available with user specified switch on illumination levels, specified switch on/switch off light levels and user specified time delays. Photocell-10 has a North facing window.
A photocell is a resistor that changes resistance depending on the amount of light incident on it. You might find these chapters and articles relevant to this topic. A photocell is a light-to-electrical transducer, and there are many different types available.
For most light-sentsitive applications like "is it light or dark out", "is there something in front of the sensor (that would block light)", "is there something interrupting a laser beam" (break-beam sensors), or "which of multiple sensors has the most light hitting it", photocells can be a good choice!
Board 3.3V to one leg of the photocell (doesn't matter which leg). Note you want to use the voltage from your board that corresponds to the maximum analog input voltage. For Feather boards this is 3.3V, but for other boards it might be higher or lower--consult your board documentation to be sure.
Photocell-10 has a North facing window. Incorporates a state of the art microcontroller and a silicon integrated photodiode and amplifier with spectral and angular response. Meets RoHS and WEEE Standards. ILA
