The document serves as an introduction to the Internet of Things (IoT), explaining its definition, growth forecast, and examples of IoT applications, particularly in agriculture like the 'connected cow.' It also outlines various hardware options such as Raspberry Pi and Arduino, and provides resources for software development. The final sections encourage building projects and include numerous links for further learning and resources.

What is IoT?
“In the broadest sense, the term IoT encompasses
everything connected to the internet, but it is
increasingly being used to define objects that "talk" to
each other.”
"Simply, the Internet of Things is made up of devices
– from simple sensors to smartphones and wearables
– connected together"

“Gartner forecasted that 14.2 billion connected
things would be in use in 2019, and that the
total would reach 25 billion by 2021”

The Connected Cow

29. IoT with only your laptop – Copyright Pete Gallagher 2020 – @Pete_Codes
The Connected Cow
“To identify a cow in heat, you need to
spend at least 20-30 minutes in the
stables, four to five times a day”

30. IoT with only your laptop – Copyright Pete Gallagher 2020 – @Pete_Codes
 Oestrus only lasts between 12-18 hours….
 Only once per 21 days
 Normally occurs between 10pm and 8am
 Traditionally detected by visual monitoring
 70% Conception Rate
 Only 55% probability of correctly identifying oestrus
 Pregnancy Rate of 39%
