The Sharp distance sensors are a popular choice for many projects that require accurate distance measurements. This IR sensor is more economical than sonar rangefinders, yet it provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital converter for taking distance measurements, or the output can be connected to a comparator for threshold detection. 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 (not included); the top picture on the right shows a shorter-range Sharp analog distance sensor with one of these cables. These cables have 3-pin JST connectors on one end and are available with pre-crimped male pins, pre-crimped female pins, and with unterminated wires on the other end.
- Sharp GP2Y0A02YK0F is an easy to use analog sensor that can detect the objects within the 20-150cm range. This is a long range sensor.Sharp sensors are popular among the distance sensors. GP2Y0A02YK0F provides a better performance according to it’s relevants.You can use this sensor by connecting it to a microcontroller’s analog pin. The sensor’s voltage output according to distance is given below.The sensor’s pins shown below are, starting from left, +5V, GND and data out.Features:
- Operating Voltage: 4.5V to 5.5V
- Average Current Consumption: 33mA
- Distance Measuring Range: 20cm to 150cm
- Output Type: Analog Voltage
- Output Voltage Differencial Distance Owerflow Range: 2.0V
