The Dagu Robot Resistance Photosensitive Sensor Module is a kind of light-controlled variable resistor. Photoresistors have photoconductivity and can be used in photodetectors. Photoresistors are made of high-resistance semiconductors.

In the dark, the resistance of the photoresist can be as high as several megaohms (M Ω), while in sufficient light, the resistance of the photoresist can be as low as several hundred ohms. If the incident light on the photoresist exceeds a certain frequency, the photons are absorbed by the semiconductor to the bound electrons enough energy to jump into the conduction band. The resulting free electrons conduct electricity, thereby reducing resistance.
