Hi guys,
I sent an invite to @anniekeerdekens for joining our group. Anniek is a good friend of mine. We studied together in the University of Leuven. Anniek did her PhD recently in machine learning and IoT devices for monitoring animal health and behavior (especially for horses).

Conventionally, the value of k is taken as sqrt(N) where N is the number of data points in your dataset. But a better approach is to take a random sample (5% of your main dataset) and use the trial and error method to find the optimal k value that works best for that particular sample.

Statistically, the optimal k value you find out in that sample should also be the optimal k value for your entire dataset.

Hey @abyrocks Nice to meet you. There are some beautiful OLED displays out in the market. You can use them in various shapes and sizes with cheap WiFi-enabled MCUs from the ESP series to build WiFi Clock. I'm not sure what your target market is and the commercial viability of this clock but the idea is good if you want to Learn By Doing

To find the optimal parameters for machine learning models, I usually use grid search. This seems like a good article to solve your problem: https://towardsdatascience.com/how-to-find-the-optimal-value-of-k-in-knn-35d936e554eb.

The simplicity it does not need a bigger footprint and does not require low bandwidth and minimal power usage

Yyoucef_ali not surprising MQTT at the top

Camila_99$$•3/11/24, 10:17 AM

Yeah me too because MQTT is like the reliable messenger of the Internet of Things world. It's so popular because it's designed to be really efficient, even for small devices and slow networks. Plus, it lets devices talk to each other in a flexible way, which is super handy for real-time stuff. Lots of people use it, it works on many devices, and it's really dependable. That's why it's so loved by developers and industries alike!

Hello, good evening, so we are studying to setting up a weather monitoring station in a remote location.
And we are looking for suitable suitable temperature sensor which will capture data for weather forecasting and climate research.
And we are confused about what would we look for
1: High-accuracy thermistor (0.1°C accuracy), fast response time (1 second), but requires additional heating power (2W) and has a larger footprint (requires a bulky weather shield).
2: Low-cost thermistor (1°C accuracy), slower response time (1 minute), lower power consumption (negligible, passive), and requires a smaller weather shield due to its compact size.
Can you guide me what is more suitable for weather station, and can you recommend specific sensor

Flo•3/11/24, 3:47 PM

I used the Bosch BME280 in the past and its all right. I think it would be enough for your purpose from what I can tell.

Flo•3/11/24, 3:47 PM

Most likely there are cheaper ones that are sufficient for you too, but I dont know them by name.

Flo•3/11/24, 3:49 PM

Also used the DHT22 and its all right too.

FFlo Also used the DHT22 and its all right too.

wafa_ath•3/11/24, 3:50 PM

please consider that the station is in one of the hottest place on earth is the sensor efficient for long period .... bcz i tried those sensor in small project but i wonder if they can handle external factors

Flo•3/11/24, 3:54 PM

I understand. Then I guess one has to look into some sort of industrial sensors that are made for extreme conditions. I sadly dont know them by name out of my head.

Hello, Good day to everyone

, so I'm thinking of setting up a small data acquisition system on a RTOS platform, like QNX or RT-Linux. I've heard that C/C++ is commonly used for this, but I'm wondering if it's worth considering Python for everything . Should I go with "all Python" , mix it with "C" for critical parts, or just stick to C? Please I need advice on this

techielew•3/12/24, 1:57 AM

I'd say it depends on your design objectives and what you're comfortable in working in but if you need to use an RTOS and are familiar enough with C, why not just keep it small and straightforward and go with that? Any @Middleware & OS folks want to weigh in on this?

Re MQTT, an honourable mention goes out to NATS and PubNub. Those are really lightweight and powerful.
