Hi everyone!

This is my first post, I've been looking for any sensor measurement for sugar for Arduino, however, I haven't found it so far.
Any suggestion would be really appreciated!

Regards

 

Hi hugalves, its sounds rather specialised to me, I think you would have to build the optics yourself from a CCD array and laser or some such.

 

Sounds specialized...Arduino is just an ecosystem.so if you get dirty enough you can interface that uC with most sensors...if it's powerfull enough to handle it...another story.....you could try looking for sensor ic's directly on the net and see if you could make a breakout board yourself.It's not going to be a walk in the park but if you have some specialized support it should work out(like electronics lab equipment access.)

 

How could that be if its powerful enought
That not even true the arduino is a ide
But the cores you can use can do anything one
Could think of. You have arm and avr
Now the truth is its up to the coder what can
And cant be done.
You can dig in as deep as one wants

Strictly speaking the Arduino dev boards are uC with support circuitry.Arduino consists of it's cores +bootladers + ide etc...software parts.And about powerful enough....that sensor might output data too fast for the 8bit Arduino uC to keep up.Maybe the 32 bit ones are a better option.
Anyway i couldn't find any glucose sensors on Mouser but you should look on Digikey also under the Biometric sensors option.

In fact, the device to measure sugar already exists, its called BRIX: https://www.amazon.com/Refractomete...ds=brix+sugar&qid=1567524256&s=gateway&sr=8-4)

I was wondering if there were any Arduino device that could attach on it and get the sugar measure from BRIX, maybe this could be a shortcut. I will figure out how do it.

Thanks everyone for replying!

 

I am looking for the same thing. There are plenty of these as hand held digital units. Digital Refractometer example
It is just a question of getting a raw sensor and talking to it. Maybe talk to Hanna instruments about it?

hi there, Have you got any success making this. I was trying to make BRIX meter using nodemcu, got across this thread.
probably you could help. tia

Hi, I'm looking for something like that too, have you found something?

 

Sugar? Then use a not refraction of light (== mirror) but specific turn of polarization plane instead. Thats an effect very specific to any sugars. Just ordinary lightsource (LED??) and polarisation filter after that. Then cuvette with LUT (liquid under test) and one another polarisation filter with after staying any photodetector (photoresistor, phototransistor etc). As larger the sugar concentration, as less will be illuminated light receptor. The transimpedance OpAmp will be needed probably, but if Your wishes are inside the 8...10 bits of accuracy, then simply switch this opamp to one of (Your choice) A0 to A7 I/O having the ADC functionality.

 

Refractive index is not specific. Other solutes in the solution will affect it. That is why the description of the device (post #10 link) is based on using pure water. The method based on near IR measurement is probably more specific.

No. I have not found anything. I have not followed up much though.
