What makes MQTT the most popular choice in your opinion?

Nnour_oud What makes MQTT the most popular choice in your opinion?

youcef_ali•3/11/24, 9:11 AM

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

Hi everyone, good morning, I want to ask what does ESC stands for and what does it do and how I can choose a better one for my flight

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?

Thank you @techielew , I am actually comfortable working with C , but i just need something faster and easier to work with, with ease in debugging.

AAditya thakekar Just stick with c

Marvee Amasi•3/12/24, 7:59 AM

@Aditya thakekar , heard of tools like Cython or SWIG ?

Aditya thakekar•3/12/24, 8:00 AM

Yes

Less the complication better it is. Start with simple things

Joseph Ogbonna•3/12/24, 9:10 AM

For a solid data acquisition setup on an RTOS, go with the main stack , your C/C++. Python might not handle the real-time stuff as well. Keep it straightforward. C is quite good and you should be able to see some example files for it than Python

I've been chatting with Brandon... I knew him in his old OSM days. We've been talking about the community and I came to check it out. My tech background--been in editing and marketing of tech for years, starting with the really geeky publication Circuit Cellar. Not an engineer, but know the s/w side of things at a pretty solid higher level.

It has got very confused datasheet and wiring. If here someone who has a few experience with that, I will be glad, thank you.

Chimmuanya Okere•3/12/24, 9:36 PM

Currently working on the power section of my schematics design. Am using a voltage regulator of 3.3v 500mA. The total power(current) of the board at full load (when operating at full capacity) is 470mA, and the regulator has a drop out or leakage current of about 50mA.
Will it still be ok for me to use this regulator or I should change to another. But the device will not always operate at full capacity, just once in a while. Will it cause any issue on the board. @PCB & Analog @MCU, MPU & Firmware
