Analog Infra-Red Ranging Sensor
The GP2Y0A02YK0F is a well-proven, robust sensor that uses angle-
of-reflection to measure distances. It's not fooled by bright light or
different coloured targets!
Simple to use (analog 0 to 2.5V output)
Small (4.5 x 2.2 x 1.9 cm)
Connects directly to any microcontroller with A/D
20 cm to 150 cm (8 to 79") range

- Page 2 Usable detection range is 10 cm to 80 cm (approximately 4” to 31.5”). The Analog Infra-Red Ranging System consists of the Sharp GP2Y0A02YK0F Distance Measuring Sensor and a custom cable assembly. The GP2Y is a compact, self-contained IR ranging system incorporating an IR transmitter, receiver, optics, filter, detection, and amplification circuitry.
