Photosensitive sensor KY-018 - Photoresistor - Light sensor module for Arduino

The KY-018 photosensitive sensor is a sensor for detecting light and changes in its intensity. Very sensitive.

The photoresistor module is used to signal the presence or absence of light.

The light sensor module allows you to easily detect light levels from the Arduino controller.

The module consists of a photoresistor (5 MOhm dark, up to approx. 20 Ohm light), which changes its resistance depending on the light intensity level, and a 10 KOhm resistor.

By connecting the power supply, we receive a variable voltage value on the signal pin depending on the light intensity, e.g. with a 5V power supply, when the sensor is fully illuminated, the output is 0V, and this value increases to 5V as less and less light falls on the sensor.

• Photoresistor
• Supply voltage 3.3 - 5V
• Analog output
• Pins: S-Out, VCC, GND
• Dimensions: 20x17x8

• - 1 piece.
