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?

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.

Marvee Amasi•5/27/24, 3:09 PM

I used to think that low-power designlow-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.

Now fixed pointfixed point math can be done purely in software using integer operations, later on saving power on microcontrollers without an FPU. fixed pointfixed point has lower precision.

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.

Daniel kalu•5/30/24, 1:03 PM

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?

Joseph OgbonnaOP•5/30/24, 2:04 PM

If you're trying to find the right connectivity consider the long term value, cost, Scalability and also power. NB IoT will require a SIM and might need more management strategies. Though it has wider coverage. So consider long term cost.

I will advise to use LoRa if the geolocation is limited within a certain region
