The goal is to make it easier to write Python scripts to read, process and act on sensor data.

Requirements

• Linux environment (like a RaspBerry Pi)
• Python3

Installation

Just clone or download the files and put them in a sios folder inside your script folder.

Examples

Read and persist sensor data from Arduino

import sios

arduino = sios.Serial('/dev/ttyACM0', 9600)
temperature = sios.Measurement()
r = sios.redis_server()

while True:
    response = arduino.send('get')

    if not response:
        continue

    gas.add(response)   # add recevied sensor value to measurement
    print(gas.get(3))   # print mean for last three points
    print(gas.mean)     # print mean for all points (300 by default)
    print(gas.stdev)    # print standard deviation for all points
    print(gas.length)   # print the number of points
    if gas.rising:      # if current measurement is outside the normal distribution (3 sigma)
        print('Rising!!')
        
    r.set('temperature', gas.get(1))  # Persist the last measurement point in Redis

    time.sleep(1)
