A sensor for waving at your gear. Leave your fans in awe of your magic majestic gestures. Reaches up to 400 cm (157 inch, 13.1 ft) distance. Has linear behaviour, resulting in a smooth output that corresponds proportionally with your movement. A digital I2C sensor, that outputs high resolution, low-noise signals. To have a range up to 5.5 meter use the ReachFar.

Requires a WiDig or USB-microDig running firmware v7.5 or higher.

Application examples

  1. Combine with lasers and make a laser harp.
  2. Measurement of the distance of objects like a hand, person or wall.
  3. 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.
  4. Pamper your robot or toy car and combine with a Orient4D to detect approaches to and/or impacts with walls and what have you.

Technical specifications

Product ReachFarD sensor
Version 1.0 (September 2018)
Sensing parameter distance, proximity
Sensing method modulated infra-red (940 nm) laser light reflectance sensor
Field of view 27 cone
Range 400 cm (157 inch) using method 1 or 5, 360 cm (142 inch) using method 3 or 7, 310 cm (122 inch) using the default method, 130 cm (51 inch) using method 2 or 6. Target (white, 88% reflectance) must cover full field of view in dark (no light) conditions.
Range accuracy 20 mm with white (88% reflectance) target. Target must cover full field of view in dark (no light) conditions.
Response time 20 ms (method 2 or 6), 33 ms (default), 100 ms (method 3 or 7), 200 ms (method 1 or 5)
Power supply 4.75 to 5.25 V DC, 19 mA at 5 V
Sensor dimensions 25 x 12 x 5 mm (1.0 x 0.47 x 0.2 inch), incl. two 3 mm (0.1 inch) mounting holes
Operating temperature -20 to 85 C (-4 to 185 F)
Weight 12 g (0.42 oz), incl. cable
Cable 1.0 m (39 inch), shielded, red wire = power, black wire = ground, white wire = sensor output, maximum extension 20 m (66 ft)
Connector male plug with a row of 3 pins in a row spaced 2.54 mm (0.100 inch)
Software support

  • Our EditorX software allows you to configure the digitizer to process and map the sensor data of multiple sensors simultaneously.

Application notes
  1. Make sure the sensor is plugged into the digitizer with the red wire connected to power. Reversing the plug may cause damage to the sensor.
  2. Requires a WiDig or USB-microDig running firmware v7.5 or higher.
  3. The default I2C address is 41 (0x29). Both I2C lines have 10 kOhm pull-up resistors.
  4. Our software enables you to use most features of this sensor. In EditorX, use the method parameter to set the sensor to output (method 0 or 4) distance with low accuracy 3 m range. (method 1 or 5) high accuracy 4 m range, (method 2 or 6) low accuracy 1 m range or (method 3 or 7) high accuracy 2 m range.
  5. Methods 1, 3, 5 and 7 measure with higher accuracy than methods 0, 2, 4 and 6. To achieve this the measurement using methods 1 and 5 take about 200 ms and methods 3 and 7 take about 100 ms, whereas the lower accuracy methods 0 and 4 take about 33 ms and methods 2 and 6 take about 20 ms.
  6. In standalone mode, methods 0..3 don't output a value if there is no object in the beam, ie. if the detected distance is the maximum range. Methods 4..7 always output a value.
  7. See also the ReachFarD function description in the firmware documentation for more details about the various methods available in host and standalone mode.
  8. For more technical specs, and to find out how to access the sensor data in detail, please consult this datasheet.
  9. For best results when using a high accuracy range method, operate under dark or at least low ambient light level conditions.
  10. The sensor will not measure the distance of objects placed behind glass (or other transparent surfaces) but the distance to the glass instead.
  11. To extend the cable, use ExtendCableD-01 and/or ExtendCableD-10.
