Product Introduction

GP2Y0A02YK0F is a distance measurement sensor module.

It consists of three parts: PSD (position sensitive detector) and IRED (infrared emitting diode) and signal processing circuit. Due to the triangulation method, the material of the measured object, the ambient temperature and the measurement time do not affect the measurement accuracy of the sensor. The sensor output voltage value corresponds to the detected distance. By measuring the voltage value, the distance of the detected object can be obtained, so this sensor can be used for distance measurement, obstacle avoidance and the like.

Technical Parameters

Supply voltage: 4.5 to 5.5 V

Power consumption: nominal 33 mA

Packing size: 29.5 × 13 × 21.6 mm

Distance measurement range: 20 to 150 cm

Signal output type: voltage analog signal

Based on the principle of triangulation

Output is inversely proportional to distance

Analog output, requires microcontroller control with AD converter

The higher the AD number, the more accurate the distance measurement effect, and the 10-bit AD can reach 0.1cm.

SD card insertion detection and write protection detection ports are all pulled out for convenient function expansion
