Self-Sustaining Spectrometer Design for Environmental Analysis
Explore the innovative design of a self-sustaining spectrometer for environmental analysis, including requirements, concept, constraints, and environmental sensors. The project aims to deliver hyperspectral responsivity, seamless integration with a custom PCB, and off-grid functionality for up to five days. Environmental sensors measure barometric pressure, temperature, and humidity, providing valuable data variations. Follow the journey of creating a remote-deployable device with an emphasis on sustainability and user-friendly interface.

tEEm Radiance Presented By: Manolo Ortiz Hayden OReilly Benjamin Reed
Spectral Forest Motivation Spectra that are absorbed or rejected by the forest. CO2 absorption. Health of the forest. There are a plethora of uses for NIR and SWIR spectroscopy. Create remote-deployable self-sustaining spectrometer.
Requirements Deliver hyperspectral responsivity in the 350 nm to 1000nm spectrum Design spectrometer electronics to be seamlessly integrated with a custom-tailored PCB Work off-grid for a minimum of five days, powered by a 12V battery Ability to sense Humidity, Temperature, and Barometric Pressure Be capable of mobile and stationary data collection and processing Must have self-sustaining Power Systems Must have a user interface
Spectrometer Concept Light will enter through a slit Reflect through the collimating mirror Light is diffracted and separated into the light spectrum wavelengths Wavelengths are focused through a mirror Wavelengths are detected by array
Constraints Budget Size Power usage Frequency interference Weight Battery
Environmental Sensors Sensors to measure barometric pressure, temperature, and humidity SHT31-D, BMP390 MicroPython Usage of I2C protocol for minimal wire usage Senors provide useful data for how measurements may vary Data will be shown on UI
