A “LDR Photosensitive Module” is most sensitive to ambient light. Generally this types of device is used to detect the intensity of the light. The D0 pin gives the digital output with build-in threshold detection circuity.
When the sensor comes in the range of the light, the digital output goes to LOW and the indication LED is turn ON. In absence of the light, the digital output goes to HIGH and the LED is turn OFF.
The whole circuity and interface is fully compatible with any micro-controller based project.
