Remotely controlled relay

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!

Remotely parts

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
