Using a raspberry pi and a few parts bought from amazon I built a weather station that can read the wind speed and direction, rain, Temperature, ground Temperature, humidity, and air quality. That then uploads them to a website for easy viewing. This no longer works because the website want $20 a month to continue using it.
I set up a WIFI network bridge using 2 Ubiquity devices to get Wifi over to the Barn then set up a router that act as an access point and switch. I then connected 2 Wifi Cameras to monitor the animals' health.
