Detects rapid light changes or light flashes. An ultra-fast way to measure the light level, with a spectral response that closely emulates the human eye. Detects upto 1,000 Lux (5 mW/cm2) within a 120°-wide cone field of view. Check the Flash sensor for a more narrow field of view.

Application examples

  1. Use for light source intensity measurement, map to a continuous controller and sweep your filters.
  2. Use with SeeLaser-Red (red beam), SeeLaser-IR (invisible beam) or any of our SeeLaser products or SeeIR (invisible beam, but for a distance less than 1 m) to create a break-beam that triggers when you cross it. Laserharp anyone ? Create a virtual cage for dancers. Or detect intruder, visitor, dog, cat, mouse .... movements.
  3. Measure room or ambient lightning.
  4. Put fish in a bowl with lights below and let the fish shadows play music (fish not included).
  5. Combine with the Hot, Air and Humid sensors to create a meteorological station. Add soil Moisture sensors and Switches to control valves for watering your plants.

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.
