You want a device, buried in sukiyaki or baked beans, to be able to communicate via bluetooth?Octradox wrote: ↑Mon Feb 12, 2018 9:29 amIs there any small device that could optimally be relatively small, have some sort of networking capability (bluetooth), battery powered, able to be made waterproof (I guess that's just any case really), and also be able to measure how warm it is, whilst being able to withstand the temperature?
Basically I want to put a device like that in my pots and pans while I cook and have that device relay back to me (on my AR helmet) their temperatures.
Wow, awesome resources! I'll probably go a thermometer attached to maybe some low powered arduino to send via bluetooth. Unsure how I'll mount it but it'll be fine.PiGraham wrote: ↑Mon Feb 12, 2018 9:44 amThere are various ways to measure temperature without the sensing device getting hot.
A thermal camera

An Infrared Thermometer

A non-contact temperature sensor
These all depend on the emissivity of the surface your are measuring. Shiny metal or clear liquid won't read as well as a mat black surface.
You can also get food thermometers designed to be inserted into food and made of food safe materials that can be properly cleaned. Some have wireless connection to a display. Some have Bluetooth and it might be possible to connect to them with Pi3 or Pi0W's onboard Bluetooth. It may be difficult to make that work.
Ooo, I'd be interested in doing that. Do you have a link to project?scotty101 wrote: ↑Mon Feb 12, 2018 9:54 amI've seen non-contact thermometers mounted above a hob before. If I remember correctly the person had used I sensor per 'hob plate' and had some form of LCD display showing the temperature of each object. Could probably be adapted to send data over a wireless protocol.
Not very very cheap, but I dont want to spend $100 on a single component (thermal camera). If the whole project costs roughly $50- $70 aud I'm happy.
