  • The GP2Y0A710K infrared sensor is a new version of GP2Y0A700K which takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 1m (39.3") to 5.5m (216.5"). The interface is 5-wire JST connector (included with pins) with dual Vcc, dual Gnd, and a single output voltage. Power, ground and signal wiring is enough to read a continuous analog voltage representing distance. A software lookup table can be implemented to translate the voltages to distances.
  • The detection range of this version is approximately 20 cm to 150 cm (8″ to 60″). The GP2Y0A02 uses a 3-pin JST PH connector that works with our 3-pin JST PH cables for Sharp distance sensors ; the top picture on the right shows a shorter-range Sharp analog distance sensor with one of these cables.
  • This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. These sensors are good for short-range detection. Infrared range finder 10cm (~4") to 80cm (~30") Analog interface Lead free, ROHS compliant Replaces the discontinued GP2D12

  • This IR reflective sensor utilizes a TCRT5000 to detect color and distance. It emits IR and then detects if it receives the echo. This sensor is often used in line following robots, auto data logging on utility meters, because this module can sense if a surface is white or black. The measuring distance range from 1mm to 8mm, and the central point is about 2.5mm. There is also an on-board potentiometer to adjust the sensitivity. The infrared diode will emmitting the infrared continutelly when the module connect to the power, when the emitted infrared light has not been reflected or the strength is not big enough,the triode will in the off state, at this time, D0 output logic LOW and the signal indicate LED off.
