If you have a Bailey caravan with an onboard tank then you will likely have been frustrated at times with the process for filling the onboard tank. I’ve made several changes to make the process more automated and in this vide I add a sound module so that the caravan can tell me once the onboard tank is full.
In the process I also explain how a buck converter can be used to lower and stabilise a 12 voltage power source.
Parts used in this project are.-
