Sharp GP2D02 Datasheet

GP2D02

GP2D02

Compact, High Sensitive Distance
Measuring Sensor

Features

1. Impervious to color and reflectivity of reflective object

2. High precision distance measurement output for direct
connection to microcomputer

3. Low dissipation current at OFF-state

(dissipation current at OFF-state : TYP. 3 µA)

4. Capable of changing of distance measuring range
through change the optical portion (lens)

■

Applications

1. Sanitary sensors

2. Human body sensors for consumer products such as
electric fans and air conditioners

3. Garage sensors
