Grove - 80cm Infrared Proximity Sensor

Code: C000137   /   Barcode: 101020042

The 80 cm infrared proximity sensor is a general purpose type distance measuring sensor.



This sensor SharpGP2Y0A21YK, boasts a small package and very low current consumption, takes a continuous distance reading and returns a corresponding analog voltage with a range of 10cm (4") to 80cm (30"). It can be used in TVs, personal computers, cars and so on.


  • Grove interface compatible
  • Wide supply voltage range: 2.5V-7V


The sensor is quite small and use a tiny connector called a JST connector. These connectors have three wires: ground, vcc, and the output. Because the sensor fires continuously and don't need any clocking to initiate a reading, it is easy to interface with any microcontroller.
