Features

• Corresponding analog voltage range from 3V when an object is 10cm (4") away and 0.4V when the object is 80cm (30") away. 

• Grove interface compatible

• Wide supply voltage range: 2.5V-7V

Description

The 80cm Infrared Proximity Sensor is a General Purpose Type Distance Measuring Sensor based on Sharp GP2Y0A21YK, which is a wide-angle distance measuring sensor. This proximity sensor takes a continuous distance reading and returns a corresponding analog voltage with a range of 10cm (4") to 80cm (30"). You can apply it to TVs, personal computers, cars and so on.

This sensor is quite small and uses a tiny connector called the Japan Solderless Terminal (JST) connector. These connectors have three wires: Ground, VCC, and Output. Because the sensor fire continuously and don't need any clock to initiate a reading, it is easy to interface with any microcontroller. for the Seeeduino 4.2, the wire converts the 3-wire to 4-wire so that it can bee compatible with the twig interface of Grove.
