![]() ![]() Lighting is variable of interest in different fields of study, such as renewable energy, indoor cultivation, chemistry, interior design, and even psychology. Finally, the sensors were mounted on a standard 2020 extruded aluminum guide rail, this rail allows to fix sensors in different distances and arrangements, bringing adaptability to the system. The sensor enclosure was standardized in installation and all of them except the AS7265 have the same size, and were covered with a 1/8” PTFE sheet to take advantage of its diffuser characteristic. The acquired data can be sent to the cloud in real-time or stored in a micro SD memory in separate files (per sensor) to facilitate its reading, each data is time-stamped using Unix format, synchronized with a Network Time Protocol (NTP) server. The system includes six multi-spectral sensors that allow 54 different measures. In this work, a modular system of sensors for UV–vis-NIR radiation measurement is presented. Due to the light spectrum influence in all these fields, it is necessary to develop instruments that facilitate their remote measurement and storage using Internet of Things technology. The device is available in an ultra-low profile package with dimensions of 3.1mm x 2mm x 1mm.ĪS7341 - 11-channel spectral sensor Eval KitĪS7341 - Spectral Sensor Eval Kit Emissive/AmbientĪS7341 - Spectral Sensor Eval Kit Reflection ModeĪS7341_EvalSW_Reflection_v1-26-3.zip Evaluation Software for AS7341 EVK Reflection Mode - Color + Spectral MeasurementĪS7341_EvalSW_Presense_v1.0.zip Presence Demo Software in Combination with AS7341 Sensor Board and Unicom InterfaceĪS7341_EvalSW_FastDemo_v2-0.zip Fast Demo Software (Flicker Measurement and Spectral Reflection) in Combination with AS7341 Sensor Board and Unicom InterfaceĪS7341_EvalSW_Aqua_v1.26.3.zip Evaluation Software for AS7341 EVK Aqua Sensor - Demo with technical Documents on StickĪS7341_EvalSW_ALS_v1-26-3.Light wavelengths like Ultraviolet (UV) and Near-Infrared Radiation (NIR) are some topics of great interest for research in renewable energy, agriculture, architecture, interior design, and psychology. The device can also be synchronized to external signals via pin GPIO.ĪS7341 integrates filters into standard CMOS silicon via Nano-optic deposited interference filtertechnology and its package provides a built in aperture to control the light entering the sensor array.Ĭontrol and Spectral data access is implemented through a serial I☬ interface. The NIR channel in combination with the other VIS channel may provide information of surrounding ambient light conditions (light source detection). The flicker detection engine can also buffer data for calculating other flicker frequencies externally. The device also integrates a dedicated channel to detect 50Hz or 60Hz ambient light flicker. 8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photo diode without filter (“clear”). 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. AS7341 is an 11-channel multi-spectral sensor for color detection and spectral analysis applications. ![]()
