The Okdo TelePort photoresistor sensor. Its working principle is that photo-sensitive elements convert light signals into electricity signals. The photo-sensitive element varies with the brightness of light. When the light brightness is stronger, the resistance will reduce
on the contrast, when the light is weaker, the resistance will rise.
