Product Summary
The Wireless Light and Color Sensor features two separate apertures: One measures ambient light from the side of the box, and the other measures percent color of directional light at the end of the box.
Features
The ambient sensor measures:
- Lux: light energy from a point in a direction (per steradian, a solid angle) per second
- Illuminance: Light intensity per area, or brightness in our eyes’ perceivable range
- Irradiance: Power of the light per area. (Depends on wavelength as UV light has more energy than infrared)
- PAR (Photosynthetically Active Radiation): amount of light in the visible range 400 -700 nm available to stimulate plant growth
- UV Index: 1 to 12 scale for the time light takes to cause skin damage. (Larger numbers cause burns faster.)
The directional spot sensor measures:
- RGB: Light levels as a percent of the total of all colors measured
- White: Total 'white' light intensity as a function of the sensor (on a scale of 65,536)
