Podcast Notes

  • Brandon Satrom
    • Developer evangelist for Particle
    • The founder of Carrot Pants Press
    • Loves to talk about Javascript, open source, microcontrollers, robots, and what ever new shiny tool or technology that is currently distracting him
    • Kitchen Sink of badges designed for Maker Faire San Mateo.
    • Favorite Bagel
  • Blinky of IoT
    • 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
      • Individually Calibrated with NIST Traceable serial number
      • 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
    • Another Particle Photon pulls data from the particle cloud and drives a relay board
    • 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
  • Other Questions
    • Future of IoT?
    • Particle Hardware Tech Details
      • Cellular
      • Mesh
      • BLE5
      • 4G
    • Why use a Particle device over a ESP32 or ESP8266?
  • Discount codes for MEP Listeners
    • Particle is giving MacroFab Engineering Podcast listeners a discount
