## Description

The Sharp GP2Y0A21YK0F is an infrared distance sensor that outputs an analogue voltage corresponding to the distance of the nearest object within its 10–80 cm detection range. Using IR triangulation, it provides reliable distance measurements independent of the target object's colour or reflectivity. The sensor connects via a 3-pin JST PH connector and operates from a 4.5–5.5 V supply, making it compatible with most microcontroller platforms including Arduino and Raspberry Pi (with an ADC). Key Features IR Triangulation – Measures distance using infrared light, not affected by target colour Analogue Voltage Output – 1.9 V typical differential across the detection range 10–80 cm Range – Reliable detection of objects within this window Fast Update Rate – 38 ± 10 ms measurement period Compact & Lightweight – Only 3.5 g Specifications Operating Voltage: 4.5–5.5 V Current Consumption: 30 mA average Detection Range: 10–80 cm Output: Analogue voltage Update Period: 38 ± 10 ms Connector: 3-pin JST PH Dimensions: 44.5 × 18.9 × 13.5 mm Weight: 3.5 g Compliance: RoHS (lead-free) Tip: Place a 10 µF (or larger) bypass capacitor across the power and ground pins close to the sensor, as it draws current in short bursts. Ideal For Obstacle avoidance on mobile robots Proximity and motion detection Object distance measurement Package Contents 1× Sharp GP2Y0A21YK0F analogue distance sensor with JST PH cable
