gp2d15 7 data sheet notes ? keep the sensor lens clean. dust, water, oil, and other contaminants can deteriorate the characteris- tics of this device. applications should be designed to eliminate sources of lens contamination. ? when using a protective cover over the emitter and detector, ensure the cover efficiently transmits light throughout the wavelength range of the led ( = 850 nm 70 nm). both sides of the protective cover should be highly polished. use of a protective cover may decrease the effective distance over which the sensor operates. ensure that any cover does not negatively affect the operation over the intended application range. ? objects in proximity to the sensor may cause reflec- tions that can affect the operation of the sensor. ? sources of high ambient light (the sun or strong arti- ficial light) may affect measurement. for best results, the application should be designed to pre- vent interference from direct sunlight or artificial light. ? using the sensor with a mirror can induce measure- ment errors. often, changing the incident angle on the mirror can correct this problem. ? if a prominent boundary line exists in the surface being measured, it should be aligned vertically to avoid measurement error. see figure 4 for further details. ? when measuring the distance to objects in motion, align the sensor so that the motion is in the horizontal direction instead of vertical. figure 5 illustrates the preferred alignment. ? a 10 f (or larger) bypass capacitor between v cc and g n d near the sensor is recommended. ? to clean the sensor, use a dry cloth. use of any liq- uid to clean the device ma y result in decreased sen- sitivity or complete failure. ? excessive mechanical stress can damage the internal sensor or lens. figure 4. proper alignment to surface being measured figure 5. proper alignment to moving surfaces gp2d15-1 (avoid if possible) (preferred) gp2d15-2 (avoid if possible) (preferred) direction of movement direction of movement
