## Description

The Sharp GP2Y0A21YK0F is an infrared distance sensor that measures distances from 10 cm to 80 cm by bouncing IR light off objects. It outputs an analogue voltage proportional to distance — approximately 3 V at 10 cm and 0.4 V at 80 cm — which can be read directly by an Arduino or other microcontroller's ADC input. Includes a 30 cm (12") JST interface cable with three wires: red (5 V), black (GND), and white (analogue output). Key Features Sensing Range – 10 cm to 80 cm Output – Analogue voltage (0.4 V to 3 V) Supply Voltage – 4.5 V to 5.5 V Current Consumption – Approximately 30 mA Cable Included – 3-pin JST connector, 30 cm length Ideal For Robot obstacle detection and avoidance Proximity sensing and object detection Arduino and microcontroller projects Package Contents 1× Sharp GP2Y0A21YK0F IR distance sensor 1× 3-pin JST interface cable Resources Datasheet (PDF)
