Application examples

1. Measurement of proximity of objects like hands or walls.
2. Great for making that fake Theremin.
3. Update your keyboard with this handy gadget.
4. Combine with a TapTiled floor, some MoveOn and/or Advance and/or ReachFar sensors and make sure every move of your visitor has an effect. The Flash + SeeLaser combo adds a touch of diamond robbery feeling.
5. Pamper your robot or toy car and combine with GForce3D, and Orient3D to detect approaches to and/or impacts with walls and what have you.
6. Create a fancy control panel by combining Push sensors (Push, Push3D), Reach sensors (Reach, ReachClose), Slide sensors (eg. Slide-50, Slide-200, Slide-500, SlideRound, SlideWide), Touch sensors (Touch, TouchMicro-05 TouchMicro-10, TouchMini, TouchMiniOn, TouchStrip) and Turn sensors to name a few.

Software support		Our EditorX software allows you to configure the digitizer to process and map the sensor data of multiple sensors simultaneously. Our Link software allows you to receive the sensor data from the digitizer and use your computer to view, calibrate, record, process and map the sensor data of multiple sensors simultaneously. Our SensorX software allows you to receive the sensor data from the digitizer and use your computer to view, calibrate, record, process and map the data of a single sensor. 08 Dec 2010: ReachClose v1.11 for MacOS and Windows from source code in Max.
Application notes		Due to the modulation of the infra-red light that is used to detect a reflecting object the sensor is insensitive to ambient light variations. Glass or other transparent surfaces can be placed in front of the sensor but for best results place the sensor as close as possible to the surface and make sure the sensor emits/receives light perpendicular to the surface to avoid reflections that distort the sensor output. Warning ! Make sure the sensor is plugged into the Digitizer with the red wire connected to 5V power. For best results, use only one ReachClose per digitizer since the current requirement fluctuates between 30 - 50 mA which creates significant power supply noise. Hence, when using multiple ReachClose with one digitizer the sensor signals will be more noisy. The number of ReachClose that can be used with one digitizer is determined by the maximum current that can be supplied to the sensors by the digitizer divided by the maximum current required by the ReachClose, ie. 50 mA.
