Ever wondered about the different types of CO2 sensors? Let’s dive into the world of NDIR, Photoacoustic, and MOX sensors and see what makes each one tick. #CO2sensors #AirQuality #technologies
NDIR (Non-Dispersive Infrared) sensors are like the royalty of CO2 sensors. They measure the amount of infrared light absorbed by CO2 molecules in the air. Fancy, right? 🌫️🔦
These NDIR sensors are known for their accuracy and stability. They don't get thrown off by humidity or temperature changes, making them the reliable friend you can count on. ✅📏
Dual-beam NDIR sensors are even cooler! They use two light paths: one for measuring CO2 and one as a reference. This helps them stay accurate by compensating for changes in light source intensity and sensor aging. Double the beams, double the fun! 🌟🔍
Then we have Photoacoustic sensors, which detect sound waves produced by CO2 molecules when they absorb light. These little guys are small, low-power, and perfect for those who need a compact solution. 🔊🔍
Photoacoustic sensors are super sensitive and provide accurate readings even at low CO2 levels. Plus, they're not bothered by environmental changes like humidity. 🌧️🎯
Now, let’s talk about MOX (Metal Oxide) sensors. They detect CO2 indirectly by measuring changes in the resistance of a metal oxide material when it interacts with gases. Think of them as the bargain hunters of CO2 sensors. 🧪💡
But beware! MOX sensors can be easily fooled. For example, if you use isopropyl alcohol nearby, they might think CO2 levels have skyrocketed. Not the best for accurate readings. 📉⚠️
Choosing the right CO2 sensor depends on your needs. For top-notch accuracy and reliability, NDIR and dual-beam NDIR are your best bet. For tiny, low-power needs, Photoacoustic sensors are the way to go. 🎯🔬

I found a tool to read the json files of my mastodon archive.
You have to download something and then open that with firefox, and then upload your archive in the thingy. I didn't have a targz file so then it's "manual" which is 4 files instead of 1. There are steps to guide you through it.
Thank you, someone at github, for making it accessible to non-tech-users.
I actually just wanted to see my own posts, without boosts, of a certain time period. This tool does that and there are some graphs too. Media doesn't show though, but you can easily open your original post via the tool.
It's this one: https://github.com/zero-mstd/mav-z
I might try calling U-Haul. I did their online thing and no matter what local zip codes I put in and what dates it told me cargo vans were unavailable.
The Enterprise person told me they quit renting them out "without a valid reason in the last few years." I guess people were tearing them up off-road. From what I gathered unless it was likely to be icy somewhere that I was driving it they weren't willing to rent it out.
Pretty sure at this point we'll just bite the bullet and let a mover handle the dozen or so things we can't fit. So far they've been pretty unphased by the idea of driving up our half mile dirt "driveway."
I thought about hosing it down so there was no dust, but in the end neither Enterprise or Penske(who were the two convenient locations) were willing rent it since it wasn't winter time.
It was really like "You want a 4WD? I'm now going to interrogate you about why!" 😂
Yeah, we're in the US. Moving up the east coast out of Governor DeSantis' "freedom state" 😉
Moving up into the hills and nature. I'll have to get some photography tips from you in the future to up my game.
I'm trying to figure something like this out. It's a 10 hour drive and I only have 12 pieces of furniture that we're bringing that don't fit in our car.
I'm asking for quotes from a couple movers and we'll see if the sticker shock kills me.
From what I'm hearing they basically only rent them out in the winter. It's bizarre to me that they own cars that they won't rent out unless you promise never to go off of a paved road, but, here we are.
I'm trying to rent an AWD cargo van to move a few pieces of larger furniture and I'm finding that all of the rental places that have them, put them behind a "call for details" so you can't reserve them online. As soon as I call they ask why I need an AWD or 4WD since it's winter time. I say that I'm moving off grid and I'm up a dirt "driveway"(call it a road and they immediately hang up on you) and they all freak out. "Take it off of the paved road and you're violating our terms of service!"

#IDMastodon #Neuroimmunology #Neuroinflammation #NeuroCOVID The prevalence of #neuropsychiatric symptoms was estimated according to a meta-analysis performed with 15 different peer-reviewed studies including 47,910 patients (age 17–87 years). Elevated levels of neurotoxic metabolites could indicate increased neuroinflammation and risk for developing neurological symptoms in #LongCovid ...

#Covid day 3. The cat is losing her mind because I won’t let her into the isolation room. But I’ll be damned if I’m giving my cat Covid.
Y’all are going to roll your eyes, but just in case anyone needs to hear it, Amazon Clinic is a steaming pile of 💩. Get your Paxlovid prescription anywhere else.
I'm actually going to be brief here. Shocking, I know.

I think these lawsuits will ramp up. I've been trying to get someone I know who's suffering, and has plenty of money, to start one himself.
I also think, based on discussions with actual lawyers previously, that there will be a day in court where in one room lawyers are saying, "Sure, you're unwell, but, how do you know that's from PFAs and not COVID?" While lawyers in the next room over are saying, "Sure, you're unwell, but how do you know that's from COVID and not PFAs?"

So our family doctor asked us — while unmasked in their office — how long we were going to wear face masks in public places. WTF!
I am not a conspiracy theorist but I have lost confidence in our healthcare system. Still getting vaccinated BTW

May 27, 2024- “SARS-CoV-2 can directly invade the cardiovascular system through ACE2; Similarly, cardiovascular diseases such as hypertension and coronary heart disease can affect ACE2 levels and exacerbate the disease, and ACE2 dysregulation may also be a potential mechanism for long-term acute sequelae of COVID-19.” “..because ACE2 is widely distributed in the human body, novel coronavirus infection can not only affect the respiratory system, but also directly invade the cardiovascular system through ACE2, causing or even aggravating cardiovascular diseases.” “Although vaccines targeting SARS-CoV-2 have been produced, the risk of disease remains high for individuals with weakened immunity.” - https://www.frontiersin.org/articles/10.3389/fcvm.2024.1409723

Only in a world that has no intention of decarbonizing does this make sense.

Just a reminder to check your local wastewater testing if it still exists. Ours does not, but the two closest to us on https://data.wastewaterscan.org are both straight vertical lines now. This new variant's wave looks like it's likely to be a big one. At least locally, brick and mortar schools are mostly finishing up this week. Maybe that'll alleviate some of the pressure.

N95 (vergelijkbaar met FFP3) mondneusmaskers en PCR testen zijn in ziekenhuis goedkoper dan chirurgische maskers en zelf-testen (en waarschijnlijk ook goedkoper dan geen maskers en geen testen).
"In other words, testing and wearing N95s to detect and prevent COVID can save lives and money because it reduces the costs of keeping patients in hospital for longer and replacing furloughed staff."
