aymen ammari•5/25/24, 3:47 PM

It can work with Max30102 in parallel right?

Ming•5/25/24, 3:51 PM

You will need a PPG for the SpO2 & heartbeat - but yes, it will work with them in parallel

aymen ammari•5/25/24, 3:52 PM

What is PPG?

Ming•5/25/24, 3:53 PM

It's photoplethysmogram - https://en.wikipedia.org/wiki/Photoplethysmogram
Here's an article on it's use - https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6426305/

Photoplethysmogram

A photoplethysmogram (PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. A conventional pulse oximeter monitors the perfusion of blood to the dermis an...

Thank you, this helps a lot

BBen There is no d21 and d22 in esp32cam

Hey everyone,

I wanted to share something exciting I’ve been learning about recently Edge AI and its impact on embedded systems and IoT. Edge AI is the practice of running AI algorithms locally on embedded devices, rather than relying on cloud processing... Have any of you worked with Edge AI? What tools or applications have you used?

techielew•5/26/24, 6:48 PM

I think @Navadeep may have used it. I did a review of it a while back with Chris Rogers. However it was years ago so a lot has probably changed since then.

So you’re an embedded or IoT developer, and there’s been an edict from on high that you need to start integrating AI into your design. And that’s about all you have to go on.

So where do you start? First of all, you’re not a machine learning aficionado or experienced data scientist. You’ve also been targeting resource-constrained embedded syste...

Marvee Amasi•5/27/24, 3:09 PM

I used to think that

low-power design

low-power design

is all about fancy hardware , but honestly Software plays a big role.
How is that ??
1. Put unused stuff to sleep

: Clock gating dims the lights on idle modules, while power gating cuts the power completely.
2. Smart task scheduling

: Try not to overwork your processor. Schedule your tasks efficiently and let it nap in low-power modes.
3. Tell peripherals to chill

:
Our Sensors and displays are energy hogs. Turn them off when you are not using them and configure them for power-saving modes also.
4. Code like a pro

: Choose efficient algorithms, use power-saving instructions, and eliminate unnecessary operations.

Yeah you'll need to conserve power. Microchip has a ready-made sleep library for AVR for those working on it https://onlinedocs.microchip.com/pr/GUID-A834D554-5741-41A3-B5E1-35ED7CD8250A-en-US-5/index.html?GUID-825A28EE-C4E4-4C03-864F-92AA9BA41231.

To keep the user's code safe, the LLM should run on his/her local computer. It should even work offline!

nour_oud•5/29/24, 11:40 AM

I think it is a great idea to integrate LLM into Embeetle, but making it work offline will not be easy or possible for everyone because it would require high performance computers. I think it would also be good if you host the LLM model and offer the AI as a service for people who can’t deploy it locally.

Hey guys currently, I am designing monitoring environmental sensors for a large geographic area. The sensors will collect data such as temperature, humidity, and air quality. Should I use LoRaWAN or NB-IoT for connectivity, considering factors such as device density, coverage, data rate, power consumption, infrastructure costs, and application requirements? Which one would be more suitable for my project to transmit this sensor data?
