IR Sensor for Obstacle Avoidance KY-032 (AD-032)

This sensor is known variously as the Keyes, KeyesIR or Keyestudio KY-032.  It is the the functional equivalent of the IrBeady IR-08H, also known as the AD-032.  The sensor uses a four pin connector, The pins are labeled: EN (Enable), out (Output), + (Power) and GND (Ground).  There are also two small potentiometers (variable resistors) on the board and one jumper (see picture
