The Qwiic NIR Spectral Sensor uses the AS7263 near infrared spectrometer from AMS for spectral identification. What can you do with NIR spectroscopy? It’s an amazing field of study and the AS7263 brings what used to be prohibitively expensive equipment to the desktop. The AS7263 should not be confused with highly complex mass spectrometers, but the sensor does give the user the ability to measure and characterize how different materials absorb and reflect NIR light. This can be useful for measuring measuring reflective indices; photosynthetic light-use efficiency is one such example.
The AS7263 is the NIR version of the spectral sensor capable of measuring 610, 680, 730, 760, 810, and 860nm of light each with 20nm of full-width half-max detection.
The AS726x is unique in that it has both an I2C interface and a serial interface with AT commands. The default is I2C but can be changed with two jumpers. We added the common serial connector so you can connect directly to a computer via USB-to-Serial if needed.
The on-board 5700k extremely bright white LED will illuminate the sample you are measuring. If needed, the LED can be disabled and a low voltage incandescent bulb can be used for better black-body illumination during readings. Additionally, the AS7263 has an electronic shutter meaning you can turn the light source (LED or bulb) on and off via software. You can also control the current to the light source (12.5, 25, 50, and 100mA) which varies the brightness enabling different exposure levels of the sample.
The Qwiic NIR Spectral Sensor has two Qwiic connectors on board. The Qwiic system enables fast and solderless connection between popular platforms and various sensors and actuators. You can read more about the Qwiic system here. We carry 200mm, 100mm, 50mm, and breadboard friendly Qwiic cables.
