I had a spare #CGM#sensor, so with my SO we now get to see the power of non-#diabetic#pancreas in action. And holy fuck, 100g of sweet bun, so I'd say 50g of carbs, +5 from milk in coffee and +5 from a biscuit, and half an hour after that they peaked at 125 mg/dL, and after another half an hour were barely above 100.
Meanwhile me after about 70g and a bunch of insulin and a bit of exercising and I failed to not go above 200 about 2h after. #diabetes#t1d
The #hydrogen#sensor market size reached US$ 401.2 million in 2023. Looking forward, Reports and Insights expects the market to reach US$ 769.2 million by 2032, exhibiting a growth rate (CAGR) of 7.5% during 2024-2032.

Hat jemand eine Idee, wie & mit welchen Sensoren ich den Use-Case "Dinge auf dem eingeschalteten Herd vergessen" im #HomeAssistant abbilden kann?
Vielleicht Passiv-Infrarot #Sensor auf den Herd richten & Anwesenheitssensor in der Küche? Wenn erster Temperatur > 60° C verzeichnet aber letzterer keine Person für 5+ Minuten registriert..?
An unexpected benefit of having an Activity Pub focused open ended project for my SE class is I get test follows.
Hi👋 everybody from #Ucsd CSE. Have fun exploring the #Fedi. #Mastodon is just part of it.
If folks have suggestions requests for some CS Graduate student teams to build something for the Fedi as a class project reply below. They’ll see it or I’ll bring it to class for sure.
OpenEarable is a new, open-source, #Arduino-based platform for ear-based sensing applications. It supports a series of sensors and actuators: a 9-axis inertial measurement unit, an ear canal pressure and temperature sensor, an inward facing ultrasound microphone as well as a speaker, a push button, and a controllable LED.
"The AirGradient DIY is an indoor air quality monitor kit enabling you to know if the air quality is healthy or not. It measures CO2, PM2.5, TVOCs, NOx, Temperature and Humidity. It’s easy to assemble, fully open-source and customizable, so you can extend it in whatever way you like."
Aha, have some ground truth available via #sensor for what the rain conditions are over there at #BurningMan. There's a CWOP station transmitting #wx station data. #NVwx
Hi everyone, in this video I connected a digital temperature sensor (DS18B20) to Commodore 64 and did some non-scientific measurements :) To make this work, I implemented a 1-wire protocol in the assembly. Enjoy :)
Doing a school assignment on a very general topic, I chose to do things around farming and it's destructive effects/how to help it using low-cost technologies. Been doing research into the possibilities of NPK (nitrogen, phosphorus, potassium) sensors as a mesh network to help map out soil nutrient levels.
From what I have seen, NPK sensors seem to be quite expensive, going in the range of hundreds. But there are models on aliexpress for under $30, so I assume it may just be a matter of distribution and manufacturing may not be that expensive. Soil moisture sensors are obviously much cheaper and can be directly built into the main PCB for such a device.
Then use something like LoRa to set them all up in a mesh network, and it seems like this could be viable for putting, say, 1 sensor every 2 or 3 acres, depending on the size of the field. Assuming $40 per sensor if there is a way to get cheap NPK detectors, that means only $1000 to cover an 80 acre field...which would pay for itself in the savings for water and the yeild after the correct amount of soil nutrients is added. Probably.
As with most things like this, actually mass-producing would be much cheaper than making a prototype per sensor, because of deals with suppliers for the sensor and such.
I am probably going to do a follow-up look into this after the assignment because I am still very interested with all this.
