Sensor Characteristics

Specifications

GP2D120 is an Infrared distance measuring sensor unit capable of measuring distance from 4 to 30cm
It is composed of an integrated combination of PSD (position sensitive detector), IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method.
