    IR sensor shows different ranges of values while on different pins

    sontung1404

      Hi, I'm having this problem. I connect this IR sensor Infrared Proximity Sensor Short Range - Sharp GP2D120XJ00F - SEN-08959 - SparkFun Electronics directly to the analog pins in my Intel Galileo board. Then I try to read the analog value through the serial monitor, and in the pin A0, the values are from 17 to 41, but on pin A5 they're from 20 to 400. Anyone knows which causes the problem or how to fix it.
