LDR Sensor Module comes with the basic components for light detection. Use it to detect the light brightness in the surrounding environment and decide to switch OFF or ON light, it can adjust the brightness. It comes with digital and analog output. You can adjust the threshold (sensitivity) of the digital output by tuning the onboard variable resistor (potentiometer). Simple usage as it is digital output, so you will know is the light is preseted and decide what to do with it.
It comes with an M3 mounting hole for ease of attaching it to any object. Onboard provides an LDR, high sensitivity and commonly being used for light detection. The module comes with power LED and status LED as an indicator.
