Slide 1 Who / What

Speaker David Thornton

I play a tech enthusiast on TV.

Sysadmin / Devops/ SRE / Scientist / Statitician / Breaker of things

My work to make an environmental sensor network in / on / around my house.

Slide 2 Idea and Goal

Collect data about "this old house".

• Temperature
• Humidity

Also collect air pressure data to better understand various physiological responses.

Side goals / means:

• Use Linux
• Use Arduino
• Use IOT - Internet of Things, i.e. small devices, smaller than a PC.
• Be visual
• Collect data over time.
• Be secure

Slide 3 The plan

this

I have implemented this using MQTT ( push ) But I settled on a prometheus http polling pattern ( Pull ).

!	Pull/Pol	Push
Pro	detect down central control / config	one two
Contra	IOT device listening all the time , power consumption two	low power, device can sleep between data collection , push events.
