Universal Electronic GP2Y0A21YK0F Sharp IR Analog Distance Sensor Cable Compatible for Arduino SUPTDescription:GP2Y0A21YK0F is a distance measuring sensor unit，composed of an integrated combination of PSD(position sensitive detector) ， IRED (infrared emittingdiode) 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.This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.Features:1. Distance measuring range : 10 to 80 cm2. Analog output type3. Package size : 29.5¡Á13¡Á13.5 mm4. Consumption current : Typ. 30 mA5. Supply voltage : 4.5 to 5.5 VApplications:1. Touch-less switch(Sanitary equipment， Control of illumination， etc. )2. Robot cleaner3. Sensor for energy saving(ATM， Copier， Vending machine)4. Amusement equipment(Robot， Arcade game machine)Package included:1pcs GP2Y0A21YK0F Compact Optical Analog Distance Detect Sensor module 10~80cmTips:Thanks your purchase from our shop，hope you will enjoy your online shopping.Please do not hesitate to contact us at first when you have any problems of our item，thanks
