In video #261 we began a journey to combine IOT repurposed TPMS pressure sensors with our Raspberry Pi to monitor our environment. The process we want to watch is the fermentation of beer. Will we be successful? In the process, we will tear down one of the sensors, and you will see some Fusion360 tricks.

The result looks great. With that little box you can monitor 4 bottles at the same time. A connecting with a Raspberry Pi is very nice, but a gadget. For a normal analog pressure meter you have to look at the physical meter any way.

Beer waste is the worst waste you can imagine! So we will set the alarm to 2bar maximum. At this stadium the beer is perfect. It depends a little bit on which beer-style you brew. A real english stout needs less carbonisation than a german Weizen - so for the stout the alarm has to be let's say ... 1.5bar. This depends also on temperature in the cellar and the amount of sugar you give in each bottle of course.

@einars899 5 жыл бұрын

@@hopfeNerd In my experience the dreaded "beer grenade" is a result of too much sugar in relation to the bottle volume and yiest strain. So the most important factor is to measure the amount of sugar accurately. I assume the temperature to be the same always. I have no experience with anything else, so cannot say what could happen. So the next project for you could be a precision sugar dispensing machine? Sorry Andreas if I added one more to your project list now. ;-)

This got me thinking of those little plastic diver toys. An air bubble is trapped in the diver and when the pressure is increased (usually by squeezing a plastic water bottle) the bubble is squashed. The mass stays the same but the volume decreases, so the density increases and the marginally bouyant diver sinks. On second thoughts, CO2 bubbles may stick to the diver, messing up the calibration. Not giving up yet.... A tube connecting the beer sample to a bottle of water to convey the pressure! Another idea: the sample doesn't need to be in a normal shape bottle, it could be in a small jar. A silicone diaphragm over the top will bulge as the pressure increases. Should be IOT-able. From à man born in the land of Heath Robinson!

Your videos are always entertaining and educational! Instead of using bottles, you might consider using cornelius kegs. That way if something goes wrong then nothing will explode (no bottle bombs). In the US homebrewers typically put part of their fermenting beer in reused and sanitized 2 liter bottles since their bursting pressure is quite high. Rather than using a pressure gauge, most can tell how much pressure has been developed by simply squeezing the fermenting plastic bottles. It’s not very scientific but it is very easy to achieve a relative measurement. Still, I’m looking forward to the next video.

As always, a great video and I commend you on the sacrifices you made in the making of this one. A question if you don't mind. Knowing the pressure is interesting and important if you are going to intervene if the pressure becomes too high. But isn't the point to prevent the bottles from bursting? Why not create a cap system that has a preset pressure relief valve that allows pressure to escape when it exceeds a preset value. Your 3D cap would appear to be the perfect beginning of that. A tire valve that uses a spring to hold back x lbs of pressure but is over come by x+ lbs of pressure would do the trick. I have brewed for many years and have never come across such a thing. I have to wonder why. Fortunately I moved to small kegs and do not miss the bottles. The cleaning, filling, worrying about pressure and the inevitable empty bottles sitting around giving away how much beer you drank is a hassle. Interesting video and now I am off so I can try to figure out how I can incorporate TPS in to something...

Reto told me that he monitors the pressure to get an overall impression on the fermentation and when the beer is ready. But you have to ask him for these "brewer specific" questions. The alarm was just an additional feature, not so important for him as he seems to have the process under control.

Idea suggestion: Make the sensor smaller and let it float in the bear and have the antenna just above the surface. Put a standard airtight cap on. You will have to make your own PCB. But the product might be even easier to use. And it will work on any dimension and styles of bottles.

@AndreasSpiess 5 жыл бұрын

Interesting idea. It would for sure work if you can get the sensor small enough (incl. battery)

Andreas, what do you think of using a strain gauge mounted on the bottles on the glass? As the pressure increases, you may be able to detect the slight enlarging of the OD of the glass. Then again, it may be so small that it's imperceptible and noise would drown out the signal.

Glass is probably too hard and does not move enough.

Interesting project. We make "pétillant naturel" wines - basically a still white wine put into a high-pressure (Champagne-style) bottle with the sugar provided by using original grape juice that was saved and put aside.. The grams-per-litre of the solution is meant to result in a specific final pressure, typically shooting for around 2-3 bar in a bottle rated for 6-7 bar. All very similar to beer I expect. I've mounted pressure gauges on various sample bottles and found that the downside of using rubber is that it spoils the taste of the contents, making it unsuitable for consumption after science is finished. Stainless steel seems to be the way to go for anything that has contact with a beverage.

@AndreasSpiess 5 жыл бұрын

Thank you for sharing your experience. So far we think, the rubber will not contact the beer. But this seems also be the case in your setup. How do you get glas and stainless steel airtight without rubber?

@gafaff 5 жыл бұрын

For the "test" bottles, we use a PET bottle with a plastic screw cap and clamp a stainless steel gauge to the top with a stainless nut underneath. The plastic of the top seems pliable enough to seal up.

That`s a nice project. What`s about an over pressure valve which is activated by the pressure alarm?

@AndreasSpiess 5 жыл бұрын

It is not mainly about over pressure. The brewer wants to know the pressure to know when the beer is ready.

@IvanIvan1974 5 жыл бұрын

@@AndreasSpiess Ok. But in the video you explained bottles can explode due over pressure. The over pressure valve might avoid this situation and the further mess. The over pressure feature could be an additional option to the pressure monitoring.

Hello Andreas! Is the pressure sensor also watertight from the pressurized side? Otherwise I see some corrosion starting there...

@AndreasSpiess 5 жыл бұрын

The data sheet does not say anything. We have to do tests. I assume the silicon on the chip has to be protected somehow. These sensors are made for the automotive industry which usually is quite picky...

Applying sensors is always interesting :-) I've been wondering if testing and using ambient CO2 sensors could be a project for you, like to check air quality and sound an alarm if windows need to be opened. You might be able to combine it with a test case of how much the CO2 ppm increases by drinking a few beers in a small room!

Prost!!!!! My only compliant, you did not evaluate or rate each beer and the one bottle of wine. Other than these minor problems, this video was excellent! Lab experiment, beer tasting, sensor research, Fusion 360 and success through failure. What more can one ask for.... It should be noted, beer taste can be altered by the level of pressure maintained. Some specialty Brewers have progressive valve reliefs. Essentially, the master Brewer begins with a high (er) vessel pressure, who then allows a small amount of pressure to bleed off, then maintained at a preset level. But that is an experiment for another day, in a explosion proof lab. 😎

2Pcs 1/8" NPT MPT Solid Brass Air Compressor Tank Fill Valve Schrader Durable from ebay. I'm sure you can find something similar closer to home. They should fit right into a plastic Grolsch cap, assuming NPT taps are available in Europe.

Good idea. Then you only have to create a hole to the bottom to enable the pressure to come to the valve.
