Subject: Seeking Recommendation for Data Acquisition System with Raspberry Pi

Hello Raspberry Pi community,

I have a specific project I'm working on and I'm in need of recommendations for the most suitable product and solution. I aim to create a data acquisition system that can efficiently collect information from sensors and seamlessly transmit it to the cloud using internet connectivity.

In my proposed setup, the collected information from sensors will be transported through wires to the data acquisition system. I would greatly appreciate your advice in identifying the ideal Raspberry Pi product for this purpose. Additionally, guidance and recommendations regarding the subsequent transmission of the data to the cloud would be invaluable.

To assist you in making suggestions, please consider the following requirements:

1. Data Acquisition: The system should be capable of efficiently acquiring and processing data from various sources.
2. Internet Connectivity: It should support internet connectivity to enable seamless transmission of the collected data.
3. Cloud Integration: The product should offer easy integration with cloud services, allowing for automated and secure transfer of the acquired data.

Considering these specifications, I kindly request your help in recommending the most suitable Raspberry Pi product for this data acquisition system. Furthermore, any additional information or guidance you can provide regarding the recommended solution, including relevant accessories or software, would be highly appreciated.

Thank you for your attention to this post.

With respect,
Daniel

What kind of sensors are you hoping to read data from?

Any of the Raspberry Pi devices with WiFi or someway of connecting to the internet (perhaps via mobile internet) would be suitable.

I would go for a "Raspberry Pi 4 Model B" with 2GB RAM if you can get one.
Recommended solution:
1. Data Acquisition: Pi4 can acquire and process data from various sources using its GPIO pins or I2C or SPI or serial interfaces, using C, python, java...
2. Internet Connectivity: Pi4 can connect to the internet via its built in ethernet or wifi, to transmit of the collected data via MQTT, web API etc.
3. Cloud Integration: Pi4 can easily integrate with cloud services IFTT, Azure IOT, Google cloud etc.

RE: Neilgl's post.... (to clarify a bit)
"1. Data Acquisition: Pi4 can acquire and process data from various sources using its GPIO pins or I2C or SPI or serial interfaces, using C, python, java..."
- very true, but a stock PI4 has no analog inputs, so it cannot read analog voltages by itself (cannot read analog sensors directly). the PI has only 3.3V digital I/O. But there are many boards ("various sources") that can be connected to the PI, communicate digital data from (for example) an A/D board as neilgl describes.

i only added this because some PI products DO have analog inputs. Some do not. The PI4 does not.

For Industrial Sensors I found a shield which works fine with analog sensors.
It works well with water level sensors, and flow meters. I used some from IFM.

It has 4 channes for 4-20mA or 0-10V and a very simple setup and software.
It works well with python, in which you can incorporate your mqtt client.

As we don’t know what the “specific project I'm working on” is, we can only give general vague answers.

Vibration sensors. Thanks for your help.

Thank you for your help. The specific project is upon collecting data from locomotive engines like Diesel Engine, Gearbox, Alternator or transmission. I want to use a Pi as a data collector and se the result live in a cloud.

How do your sensors provide their information (serial, i2c, voltage, etc)
Any links and people can tell you the easiest way.
Once you know if they can be connected easily, the rest is just software and you can look that up.
