Create sensor data for a IoT project

[DeaD_EyE]

I work currently on a project, where I receive measurement data over a serial interface.
Generating random Test-Data is not very good, because it will be very noisy.

Example:
   

import random
import matplotlib.pyplot as plt


def random_delta(size, start_value, min_delta, max_delta, precision=1):
    value_range = max_delta - min_delta
    half_range = value_range / 2
    for _ in range(size):
        delta = random.random() * value_range - half_range
        yield round(start_value, precision)
        start_value += delta


plt.plot(list(random_delta(200, 10, -1, 1)))
plt.show()
