IR distance ranger covers 1 to 20 cm:  04/11/02 EDN Design Ideas  /  (added 1/05)  Commercially available IR distance rangers typically handle a 3to 30-in. detection distance. Many times, it is necessary to determine smaller distances. The circuit in Figure 1 is useful for measuring small distances to reflective surfaces. Its measurement range is from less than 1 cm to approximately 20 cm for a flat, white surface. ...
