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").
Who Viewed This Also Viewed
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
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.
