Sharp GP2Y0A21 IR Distance Sensor for Arduino (10~80cm)

The Sharp distance sensors offer remarkable precision for projects requiring accurate distance measurements. They stand out as a cost-effective alternative to sonar rangefinders, providing superior performance compared to other IR options. Featuring a straightforward setup, this sensor's single analog output easily connects to a microcontroller’s analog-to-digital converter for measuring distances or to a comparator for threshold detection.

This sensor effectively measures distances ranging from 10 cm to 80 cm (4" to 32"), delivering reliable results for various applications. The sensor’s output voltage is plotted against distance, providing clear feedback to calibrate your devices with precision. Whether you're gauging object proximity or designing motion-sensitive systems, this sensor offers dependable feedback.

Equipped with a 3-pin JST connector, the GP2Y0A21 effortlessly joins with a compatible 3-pin JST cable for integration, though soldering three wires to the sensor’s connector pins can also establish necessary connections. The sensor layout is straightforward: from left to right on the back, the pins allocate for power, ground, and output signal, making installation intuitive. This sensor is also shipped with a practical JST cable for immediate use.
