ReachOn v2.1 $19.09US $15.27US
excl. sales tax

This sensor will detect the proximity of your hand or finger, even through a thin cover. Use it as a button to switch on/off sounds and visual effects. Design your own custom control panel with the buttons hidden behind it. For a smaller version, see the ReachMiniOn. Connect larger conductive surfaces, eg. made of tin/alu foil, PCB (printed circuit board) material, conductive rubber, conductive fabric, etc., to either version to create touch sensitive panels and objects. See the video below. For a similar sensor with 12 inputs for touch pads, check the ReachOnD. If you need a larger range and want to know the approximate distance of the finger or hand to the sensor try the Reach.

Application examples

  1. Place right below the surface of the cushion of a seat and capture when somebody sits on it. Place it in the back rest and capture whether the person leans back.
  2. Create a giant pin-ball machine game: cover a ball with conductive paint, connect a ReachOn to each pin or pole (must be made from electrically conductive material, eg. metal), and let the ball hit the pin .. and trigger the ReachOn.
  3. Connect to various types of fruits and make a fruity loops controller or drum machine.
  4. Connect to plants or the pots in which they are located and re-create the legendary Interactive Plant Growing installation by Laurent Mignonneau and Christa Sommerer.
  5. 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

  1. Our SensePlay software is a very easy way to quickly map sensor data to (sequences of) sounds, images and videos using a drag & drop user interface.
  2. Our EditorX software allows you to configure the digitizer to process and map the sensor data of multiple sensors simultaneously.
  3. 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.
  4. 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.

Application Information

  1. Can be placed on or near to other electrically conducting objects to make them sensitive to touch as well through capacitive coupling. Can also be galvanically connected to other electrically conducting objects to increase sensitivity such that reaching near (but without touching the connected object) is detected by the ReachOn. After changing the electrode, re-power the sensor to allow the sensor to adjust its calibration to the new electrode.
