Introduction: Gray scale sensor is a electronic module to distinguish colors by detecting blackness. It outputs continous analogue signals, which is then changed by A/D connector into readings displayed via RCU. Users can distinguish colors by comparing the readings. It acts well in line-tracking game, with wide range of working voltage, when there is no serious environmental light interference

Feature

1 Reduce the influence cansed by environmental lights, such as sunlight, lighting.
2 Wide working voltage range of 4.5V-5V
3 Output continuous analog signal.
4 The lighting indicator marks out the port with maximum data.
