I could not wait for the back order so I purchased from Amazon. I am hoping that my grand and great grand kids will be interested in the results and how it works. I currently have it connected to one of my WIO Terminals via a MUX board. I can see the results on the display and it also writes the data to the internal Micro SD Card with TABs easily transferred to a spreadsheet. Several items being tested are coffee, hot chocolate and filtered H2O, tap H2O, Well H20 and several brands of purified drinking water. I will try to post my example in the Forum. I also may try just connecting the Triad directly to the Grove I2C connector.</p>

I am working on an undergraduate research project, and we're sending a payload up to 10,000 feet to collect data. I was wondering if this sensor can be used on open air, or if it will only work on solids/liquids? Thanks!</p>

1- how to calibrate your data and make sure of what I'm getting is right before I start measuring
2- Is there a similar product that covers the MID IR spectral range (15000-2500)nm (20-120)THz
3-If I would like to use this spectrometer as a tranmsission spectrometer can I buy the detectors seperatly?</p></p>

I know I could do this myself, but I figured other people might want to know that too. The code, as it is, reads all ranges in one function call, from my understanding of it. Maybe ill try to work this out and share it somewhere. I imagine this would do alot for the precision of the readings. This might even allow this sensor to do some readings related to atomic absorption spectroscopy, which is extremely powerful. Thanks again, this has actually inspired me to get back to this idea. Now I just need this sensor to be available again haha.</p>

Thanks for the response. I am definitely picking one of these up, see if I can try to pull out the the kind of data I had envisioned.<p>By the way, thanks for a great site, store, and resource. This has always been my favorite site, due to the quality of your products and the range of depth of your tutorials. I recently used the eagle tutorials on here to design my very first PCB, a VNH5019 Motor Driver board. Not too pretty, but it handles 10-20 amps so I am proud. So thank you.</p></p>

I added a bit to the description to try to capture spectrophotometer.<p>Welcome to electronics! I'm glad you had a project to get you started. That's how I always learned best. Sorry to hear this product sort of usurped your idea :/ Technology has a way of doing that...</p><p>I hope you can find good applications for the Triad. It's a fun, powerful sensor today, and I'm excited to see where the sensor world takes us in the next 2-3 years.</p></p>

Great job by the way guys.<p>I was trying to make this exact thing for like 2 years. Unfortunately when I started I knew exactly nothing about electronics. The whole reason I got into electronics was because I had the idea for a cheap photospectrometer to be used in water quality analysis. Damn, o well. Bravo. I was even planning on using these AMS sensors for the first iteration after I saw it on mouser and emailed AMS about it, then once you guys released your sparkx spectral sensors and I saw another cheap and easy spectrophotemeter in the wild I knew Id never catch up. You guys should make a water proof container that allows water analysis, although the light source has to be much bigger.</p><p>The applications of this in water chemistry and water quality are huge, although the precision would have to be bumped up. AMS has a couple other options, which of course make it much more complicated. Distributed sensor networks analyzing our water distribution networks, or wastewater, or streams and rivers for water quality would be BIG government contract style money. That market is still there, but im still relatively useless in electronics. Water is my thing.</p></p>

Mass spectrometers use magnetic fields and the velocity of accelerated ions to determine mass. As photons are without mass, photon spectrometers utilize the wavelength to diverge the light based on energy. Sorry to pick at nits.</p><p>Thanks!</p></p>
