Typical applications

  • Home Automation
  • Industrial Automation
  • Distributed systems


Typical connections

Many relay boards can be easily connected in one wire network to computer in the way shown bellow. It must be used some Computer<->One Wire converter. For example we have such 1-Wire converter in stock (not included in this auction) but any other one-wire converter could do the job.


Of course any microcontroller architecture supporting 1-wire network could be compaitable with the relay boad as well.



Device overview




There are many 1-Wire software available for this relay board. One such sofwtare is OneWireViewer. With this software, it can be just easily tested and simple turn on/off commands can be executed.


Denkovi 1-Wire command line tool

We have created as well special command line utility for this 1-Wire relay board. The main goal of this project is to help you to use our 1-Wire relay boards easily and without any specific knowledge how do they work. It works on Windows/Linux.

Typical applications for this software are:

  • Create desktop icons to turn particular relays
  • Create BAT/BASH files to make more complex logic (like timers for example)
  • The commands can be executed from PHP script
  • Control our 1-Wire relay boards from Android / iPhone mobile devices
  • The 1-Wire relays can be controlled from each software/platform which can run external executable files or commands in command line promt
