AtlasScientific is an abstraction layer atlas scientific devices. Any atlas scientific can be used, although the checked ones are supported with easier and optimized APIs.
- PH circuit
- EC circuit
- Temperature circuit
- ORP circuit
- Dissolved oxygen circuit
- Carbon dioxide Sensor (CO2)
- Pressure Sensor
- Flow Meter Totalizer
- Color Sensor
Disclaimer: This library only supports i2c mode.
NOTE: Although they aren't "supported" you can still use this library to access them easily. See usage.
Add this line to your application's Gemfile:
gem 'atlas_scientific'And then execute:
$ bundle
Or install it yourself as:
$ gem install atlas_scientific
There's a base class for any AtlasScientific device which can be used like this:
require 'atlas_scientific'
# The path parameter will automatically look for the first `i2c-*` device in your `/dev` folder.
# But you can also explicitly pass it as an argument:
pressure = AtlasScientific::I2CDevice.new(0x6A, path: '/dev/i2c-1')
pressure.take_reading # => 12.3
# enable/disables the LED
pressure.l # => "?"
# A lot of "default" commands are support through methods, e.g. cal, factory, i, find, o, status etc.
pressure.i => "?I,psi"
# If there happens to be a command which is not implemented as a method, you can call "execute":
# This command will change the output of the pressure unit sensor as specified in the datasheet.
# On page 46: https://www.atlas-scientific.com/_files/_datasheets/_pressure/EZO-PRS-Datasheet.pdf
pressure.execute('u', 'bar')There are also better abstraction classes for the checked circuit/probes at the top:
# Automatically takes the default I2C address of the PH circuit (0x63)
# The default i2c addresses can be found in the datasheets of the circuits
# E.g. PH: https://www.atlas-scientific.com/_files/_datasheets/_circuit/pH_EZO_Datasheet.pdf
ph = AtlasScientific::PH.new
ph.slope # => 7.58
ph.take_reading # => 7.58
ph.take_reading_with_temperature_compensation(29.3) # => 7.49After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
