Skiff: It's your best defense against the aliens' favorite form of research. The probe. You put it...
This gem provides a simple interface to a DS18b20 temperature probe, installed on a Raspberry Pi via the One Wire interface.
Installation
Add this line to your application's Gemfile:
gem 'skiff'And then execute:
$ bundle
Or install it yourself as:
$ gem install skiff
Usage
# Under Raspbian, the temperature readings are typically
# written to /sys/bus/w1/devices, so that is the default location.
#
# If you need to change it, pass your location in when you create
# the ::Skiff::Manager like this:
# manager = ::Skiff::Manager.new your_probe_location
manager = ::Skiff::Manager.new
# to get a list of all the attached probes:
probes = manager.probes
# probes => ["28-0115649922ff", "28-021564c24bff"]
probe = manager.create_probe(probes.first)
# returns an instance of ::Skiff::Probe
# to get the raw temperature of a probe:
temperature = probe.temperature
# or in fahrenheit
fahrenheit = probe.fahrenheit
# and to get all the raw data
raw_data = probe.raw
