Light dependent resistor or LDR is a light-controlled variable resistor. As the intensity of the incident light increases, the resistance of the LDR decreases. The LDR board which is available with the OpenLlab platform consists of a sensor that changes its analog output value based on the intensity of light. eg: Application to detect the presence of light and its value.

* Operating Voltage – 5V
* Sensitivity of LDR is adjustable
* Stackable headers with 3rd pin blank.
* Output type is analog
