Measure the intensity of ambient light with this sensor that approximates the human eye response curve to light. It can separately measure infrared and full-spectrum (infrared and human-visible) light. A digital I2C sensor, that outputs cailbrated, high resolution, low-noise signals.
Application examples
- Measure room or ambient lighting.
- Put fish in a bowl with lights below and let the fish shadows play music (fish not included).
- Combine with the Hot, Air2D and Humid sensors to create a meteorological station. Add soil Moisture sensors and Switches to control valves for watering your plants.

| Software support |
- 23 Jul 2019: Light2D v1.12 for MacOS and Windows from source code in Max. For multiple sensors or sensor outputs, run multiple instances of the application, each started in its own folder. Requires a digitizer with firmware v7.61 or higher (but lower than v8.00) or v8.11 or higher. Use together with Connect (MacOS / Windows).
|
| Application notes |
- 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.
- Requires a digitizer with digital (I2C) ports, eg. the USB-microDig or the Wi-microDig.
- The default I2C address is 57 (0x39). Both I2C lines have 10 kOhm pull-up resistors.
- Our software enables you to use most features of this sensor.
- See the Light2D function description in the firmware documentation for more details about the various methods available in host and standalone mode.
- For more technical specs, and to find out how to access the sensor data in detail, please consult this datasheet.
- To extend the cable, use ExtendCableD-01 and/or ExtendCableD-10.
