  • Parker unboxed a Particle Photon
  • Included in the box is a photoresistor, a LED, breadboard, and some resistors
  • Parker built the circuit and programmed the Photon in under 5 minutes
• Building an IoT Device
  • Spec Sensors 3SP Ethanol 1000
    • Low Power Consumption of around 10 to 50 uW
    • 0-1000ppm Ethanol range
    • It has 3 analog outputs 
      • Vgas which is proportional to the gas we are measuring
      • Vref which is around half the supply voltage and is used as a fixed zero reference
      • Vtemp is the temperature of the sensor used to set the temperature compensation
  • Particle Photon reading the analog outputs of the Spec Sensors 3SP Ethanol 1000
    • Posts to the cloud about the status of the sensors
    • Code for this can be found here
    • Issues porting the Arduino Code to the Particle Platform 
      • Floats -> Doubles
      • Particle.Variable do not show up if you are doing Particle.Publish too fast
  • The relay board is connected to an industrial light tower 
    • Light tower - NPTL5-W-E 
      • 24V
      • Pull down I/O lines to turn on lights
