In my sailing boat there is many thinks which I want to move by remote systems. First I have of course in boat internet router through which knowledges move. In addition need 12Vdc Microbit controlled relay which controls different thinks!
Via that Microbit remotely controller I can electrity two 220Vac electrical boxs, measurement some temperatures and some on/off infos. In this foto you can see in big box tree 12Vdc/220Vac control relay ( one is in reserve )
There are five relay operations:
- Charger the battery
- Outer light
- Boat heater
- Reset my boat computer
- Space
Three different temperature ( max is 8 )
Two on/off knowledges
