The Grove 80cm Infrared Proximity Sensor is a general-purpose distance measuring sensor based on the 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 more!

This sensor is quite small and uses a 3-pin JST connector. These connectors have three wires: Ground, VCC, and Output. Because the sensor fires continuously and doesn’t need any clock to initiate a reading, it is easy to interface with any microcontroller.

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
• Weight: 9g
• Product number: Seeed101020042
