Wide supply voltage range：2.5V 7VThe 80cm Infrared Proximity Sensor is a General Purpose Type Distance Measuring Sensors、 this sensor takes a continuous distance reading and returns a corresponding analog voltage with a range of 10cm（4"） to 80cm（30"）. Can be used in TVs、personal computers 、cars and so on.
【Interface】
This sensor is quite small and use a tiny connector called the Japan Solderless Terminal（JST） connector. These connectors have three wires：ground、 vcc、 and the output. Because the sensor fire continuously and don't need any clocking to initiate a reading、 it is easy to interface with any microcontroller. for the seeeduino、 the wire convert the 3-wire to 4-wire 、to compatible with the twig interface of Grove .
