An Industry Example…

25. Getting started with IoT with only your laptop – © Pete Gallagher – PJG Creations - 2019
The Connected Cow

26. Getting started with IoT with only your laptop – © Pete Gallagher – PJG Creations - 2019
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”

27. Getting started with IoT with only your laptop – © Pete Gallagher – PJG Creations - 2019
 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%
