Description
Reflectance sensor consisting of array 9 QTR optocouplers with the ability to individually control the brightness of each of the infrared LEDs. The sensors on the board are high density (HD) and the distance between them is 4 mm. The module can be supplied with the voltage ranging from 2.9 V to 5.5 V and draws current up to 155 mA. The optimum distance from the sensor to the ground is 5 mm and the maximum distance is 40 mm. The module is ideally suited for detecting changes in light reflection, so it can be used for edge detection or line tracking in linefollower robots.
