Visible Light Spectrum Sensor

A compact single shot complementary metal oxide semiconductor cmos spectral sensor for the visible range wavelength 400 700 nm is presented.

Visible light spectrum sensor.

Visible light applications 400 to 700 nm typically employ cmos image sensors a substrate that allowed the pixel pitch of visible light sensors to shrink quickly giving ever greater resolutions. Node chroma ams is an austrian based sensor company which has a series of spectral sensors that use xyz tri stimulus technology that can measure light waves in the vis and ir both nir and mir ranges. Temt6000 visible spectrum ambient light sensor this is the temt6000 an ambient light sensor which is sensitive to the visible spectrum. Infrared with wavelengths from 700 nm 15 000 nm and x ray with wavelengths of 01 nm 10 nm penetrate deeper into an object providing information about its internal structure.

Visible light sensors detect all light that falls in the visible light region of the electromagnetic spectrum. Spectrum offers a full line of affordable measurement technology for soil compaction soil moisture nutrient levels light weather and other factors directly affecting plant development. Visible light applications 400 to 700 nm typically use cmos image sensors a substrate that allowed the pixel pitch of visible light sensors to shrink quickly giving ever greater resolutions. Traditionally image capture in the swir spectrum couldn t be done using the same sensor technology as for visible light.

Detect trees of green and red roses too with the new adafruit as7262 6 channel visible light color sensor breakout. This sensor from ams has 6 integrated visible light sensing channels for red orange yellow green blue and violet. These channels can be read via the i2c bus as either raw 16 bit values or calibrated floating point values. Our external sensors can record rainfall leaf wetness hours temperature and humidity fluctuations and other weather events with our watchdog data loggers.

The temt 6000 is a silicon npn epitaxial phototransistor in a miniature transparent mold for surface mounting which can be mounted onto a printed circuit board. This is the light range that our eyes can naturally see. They have a series of sensing engines which include the as7261 xyz ir the as7262 6 channel vis and the as7263 6 channel vis nir. Such measurements enable lighting engineers to specify the optimum light level for human comfort eliminate excess lighting and ultimately save energy.

In addition our visible light sensors detect the entire visible light spectrum accurately measuring photopic and scotopic energy.
