K$123$ is light intensity measurement sensor$.$ The sensor can measure from no light to $1000$ Lux. Sensing element is a light dependent resistor with a sensing area of $2m{m}^2.$ It is operated with $5$ V supply. The output voltage is ground level for no light and $5$ V for a maximum illumination. The sensor can measure $1$ lux changes accurately.
