System of fog nodes to display real time temperature, humidity, and barometer sensor data on a user-friendly dashboard.
This system allows for collection and processing of data over a limited-internet area on a ski slope or other user destination.
Users can view the data of each sensor individually, history of each sensor, or an overview of all of the data.
Currently implemented:
Rangefinder
Thermometer
Pressure sensor

Download dependencies and development version of npm
In addition to dependencies of BITS, user also must have
MongoDB bits module: https://github.com/LGSInnovations/bits-mongodb
bits-weather-dashboard
bits-settings: https://github.com/LGSInnovations/bits-settings
pyUSB: https://github.com/pyusb/pyusb
Install BITS with instructions from README at https://github.com/LGSInnovations/bits
Install bits-weather-dashboard as a BITS module from https://github.com/callie-jones/bits-weather-dashboard
Tests will be run automatically when running bits-weather-dashboard with bits.
A total of three sensors were used for this project, a thermometer, scale, and microbit. A barometer was also experimented with. All sensor drivers can be located at sensor_drivers/.
The thermometer used was a TEMPer2 Thermometer. The drivers are located in sensor_drivers/thermometer, which is a clone of petervojtek's usb-thermometer git repository. Installation instructions can be found in its README.
The scale used was a 100 lb Dymo Digital Shipping Scale. The drivers are located in sensor_drivers/scale/scale.py. This driver was written from scratch in python3.4 using the pyUSB library.
Three microbits were used to simulate a rangefinder or depth sensor. The microbits were designated Top, Bottom, and Send. The Top microbit sat at the theoretical maximum snow height, and the Bottom sat at the zero height location. The Send microbit sat between the other two on a slidable arm that could be moved up and down, toward either of the other sensors. The Send microbit sent out a bluetooth pulse at regular intervals, which would be recieved by the Top and Bottom. The Top and Bottom sensors would then write the strength of the signal to serial. Both the source code and compiled microbit code can be found in sensor_drivers/microbit/.
The serial strength values are interpreted using the python2.7 script found at sensor_drivers/microbit/microbit.py. This script combines the strength values from both the Top and Bottom microbits to estimate the approximate height of the Send microbit using an experimentally found algorithm.
The project also experimented with the Cygnal Integrated Products HT163 Barometer. Unfortunately, no linux drivers could be found, and attempts to write one from scratch failed.
