Description
Light is one of the essential elements for all living beings. Therefore, it is common to work with light sensors when learning about electronics. A simple light sensor consists of a light-dependent resistor (LDR) and a sensor on the breakout board for easier connection. As the name suggests, an LDR changes its resistance depending on the amount of light it is exposed to. The light intensity and resistance are inversely proportional: the more light it is exposed to, the lower the resistance. In bright light, the resistance can be a few hundred ohms, while in darkness, it can reach several thousand ohms.
The main advantage of this board is that it provides both digital and analog outputs. By adjusting the potentiometer on the board, you will receive a digital signal within the sensitivity range set by the potentiometer, while the sensor continuously provides the analog output directly from the sensor.
