Package Included

- 1 x Optical Sensitive Resistance Light Detection Photosensitive Sensor Module KY-018 KY018

Description

- Includes an LDR-resistor (Light-dependent resistor), which decreases its resistance at brighter surrounding.
- You can determine the resistance of the resistor by using a voltage divider, where a known voltage will be divided between a known and an unknown variable resistor. You can calculate the resistance with the measured voltage - the code example below includes the exact calculation.
