Create sensor data for a IoT project

[DeaD_EyE]

A:) I'm trying to simulate 5 factories... 100 sensors min each, maybe more towards 200/300... pushing data every minute, I'll have collector processors that in this case would actually run this random generate code (in real world they would be getting data from the sensors.

I guess you can do this with my example (you've to modify it). You need to know the rate of change. For example a temperature sensor never jumps from 0°C to 100°C.

For gas sensors there is the T50, T70 and T90 value.

Response Time (T50) refers to the time it takes the sensor to respond with an output signal that is 50% of the full value of the gas being detected; i.e. if the sensor is exposed to a methane concentration of 2% by volume, it would take the sensor 10 seconds to give an output equivalent of 1%

I guess you've already the specification, which sensors to use.
You have too know about the characteristics, then you can model a value-generator for it.
Here is an example: https://cdn.sick.com/media/docs/8/68/668...041668.PDF
Response Time: (T50) 10 seconds

So my example is not enough, because the time is missing.
Measuring temperature is not an easy task.
