CNY70 Reflectance Sensor


CNY70 Reflectance Sensor


SKU: SEN-117 - Mfg Part Number: CNY70


The CNY70 is a simple reflectance sensor with integrated infrared LED and phototransistor. This all in one sensor can be used as a part of a line following sensor array, short range object detection, edge detection, and even as a part of an optical wheel encoder.

Object detection can be done fairly reliably within 5mm but ultimately the distance will vary depending on the reflectiveness and color of the object. White and light colors will reflect the IR light, while black and dark colors will cause the IR light to be absorbed. The phototransistor has an integrated daylight blocking filter that helps boost performance in brighter environments.

Because of its small size, these can be packed together to form a fairly dense sensor array.
