Clone this repo

https://github.com/uva-hydroinformatics/FloodWarningSystems_20-21.git

Install Dependencies

pip install -r requirements.txt

Obtain local copies of http_config.py and rds_config

Usage

Read Sensor Data and Update Database

Read past 3 days of data from the pressure sensor

import http_get, payload_parser, update_db
pressure_data = http_get.get_data('pressure', '3d')  
transformed_pressure_data = payload_parser.parse_data(pressure_data)
update_db.upload_pressure(transformed_pressure_data)

Update Sensor Sampling Period

Update sampling period of pressure sensor to 600 seconds

import http_post
http_post.update_sampling_period(downlink_urls['pressure'], 600)

Download Data from S3

Download device readings over date range (requires aws access keys)

import downloadS3
downloadS3.download_from_S3('dl-pr-26_5100', start_date='2021-02-23', end_date='2021-03-01')

Download last day of device readings

downloadS3.download_from_S3('dl-pr-26_5100', last='1d')

Combine device readings into single JSON, assuming local SensorData directory already exists

import combine_json.py
combine_json.combine_json('dl-mbx_5248', start_date='2021-01-31', end_date='2021-02-01', file='pressuredata.json')

Download and Combine

import downloadS3
downloadS3.combined_readings('dl-pr-26_5100', start_date='2021-01-31', end_date='2021-02-01')
