How to Connect a Light Sensor to the Raspberry Pi
Today we're creating our own LDR light sensor circuit on the Raspberry Pi. This circuit can be used in different projects that involve monitoring light levels. We'll go over everything you need to get started and even share a few project ideas along the way.
What is a light sensor?
A light sensor is a kind of photodiode. These components convert light into energy. The output from a photodiode can be measured and used to trigger specific functions.
In basic terms, these are diodes that detect light and give an output based on the level of light they receive. We can use the output in custom programs and projects.
What can you use a light sensor for?
Light sensors can be used for tons of cool projects! For example, they can trigger night lights or even help you monitor the light levels within a given space.
