Python package for managing and interacting with Resensys SenSpots.
Project description
SenStream (v 1.4.5)
SenStream is a python package for managing and interacting with Resensys SenSpot devices. Streamline data flows from SenSpot technologies and high-level data pipelines with this high-level software development kit.
At a high level, the SenStream project is designed to bridge the gap between the structural/civil engineer and the software developer for structural health monitoring and other scientific applications. This package comes equipped with the following features for SenSpot management, custom time streams, and state-of-the art time series machine learning tools:
API Functionality
- Extract and configure SenSpot parameters.
- Pull time streams from SenSpots from the cloud
Installation
Requirements
We recommend that you have a version of python >= 3.7 installed on your machine before proceeding. If the below pip
command does not automatically install pandas
and numpy
, you should make sure that these libraries have been installed before proceeding.
Install using pip
To start using SenStream install using pip:
pip install senstream
pip
is the de facto and recommended package-management system written in Python and is used to install and manage software packages. It connects to an online repository of public packages, called the Python Package Index.
Note the pip
refers to the Python 3 package manager. In environment where Python 2 is also available the correct command may be pip3
.
Getting Started
The following demonstrates what you need to get started with a connection to the Resensys cloud and check that you can extract data.
# import the necessary libraries and modules
import numpy as np
import pandas as pd
from senstream.resensys import Resensys,Sensors
from senstream.senspot import SenSpot
# for users with SenScope license, specify username and password
username,password = "test_user","user_password"
# create a client connection to resensys.net
client = Resensys(username,password)
# create Sensors object to check all sensors in present account
sensors = Sensors(client)
# get list of all devices in the client account as pandas dataframe
sensor_df = sensors.getSensors(format="dataframe")
# print list of all the sensors in the account
print(sensor_df['DID'].tolist())
View all active site registered for current user:
sensors.getSites(format="dataframe")
View current routing parameters for SenSpots:
sensors.getRouting(format="dataframe").head(5) # display first five records
SenSpot Object
Create an instance of a SenSpot object by referencing the previous client connection and specifying the device ID of the SenSpot from the user's sensor list.
senspot = SenSpot(client,"15-03-27-74")
Get the name assigned to the SenSpot:
senspot.getName()
Returns string.
Get the site ID assignment for the SenSpot:
senspot.getSite()
Returns string of format "xx-xx" with site ID.
Get the local address assigned to the SenSpot (useful for wireless routing):
senspot.getLocAddr()
Returns int.
View all available quantities associated with SenSpot:
senspot.getQuantities()
Returns [string]
Check current calibration coefficients for SenSpot:
senspot.getCoefficients()
Returns dict
Get general device summary of SenSpot:
senspot.getDeviceInfo()
Returns dict
Extract Time Series from SenSpot
- df_name: quantity being pushed by the SenSpot (complete list given by calling getQuantities() method)
- time: options = "1hour","2hour","6hour","12hour","24hour","48hour","1week","2week","4week","6month","12month","2year","custom"
If you choose a custom time range, then you must specify additional parameters:
- t_s: Start Time (UTC) (e.g. "2020-09-21 17:00:00")
- t_e: End Time (UTC) (e.g. "2020-09-21 17:00:00")
Example to pull previous two weeks of data for SenSpot quantities "Strain-xx-high_rate" and "Internal Temperature"
ss_strain = senspot.timeStream("Strain-xx-high_rate",time=["2week"])
ss_temperature = senspot.timeStream("Internal Temperature",time=["2week"])
Returns pandas.DataFrame object.

Contributing
Your contributions are highly appreciated. Please create a pull request on GitHub. Bigger changes need to be discussed with the development team via the issues section at GitHub first.
State here if contributions are welcome. State the requirements a contribution should meet to get merged.
Details about development, like creating a dev environment or running tests, also belong here, for example:
For development, you should use pipenv to keep your Python packages separated in different environments. First install pipenv via pip
pip install --user pipenv
Afterwards run
pipenv install --dev
in the checkout directory of PROJECT (the directory containing the Pipfile) to install all dependencies including the packages only required for development.
If there are more specific suggestions for development or guidelines for contributions, consider sending an email to thomas.wade@resensys.com.
