Switch on/off over internet

[tovjreddy]

Can any one give me a working circuit to switch a 3 phase motor at my farm house over internet ?

Thanks in Advance.

Good Afternoon,

I don't know where you are from, but you can try and get something like this where you are.

**broken link removed**

You can run it with a relay to switch on and of from where you like.

To turn things on/off over the internet I use one of these $100 boards.

There are several similar boards for sale.
The output is 0/5 volts that need a transistor and relay to drive your motor.
You will need to learn a little about the internet and TCPIP. The board comes with software that works and will do what you want. I modified that software to get a home control system working. (I don't know much about HTML programming) See my system at

(This is a copy of my system not the real thing! I don't want you turning lights on in my house)

i was looking for something else when i came across this sounds fun . but the link is dead any chance of an updated link.

thanks

theese seem pretty good https://www.olimex.com/Products/PIC/Development/PIC-MAXI-WEB/ i have had one since christmas but havnt done much with it yet

@Ronsimpson

You are talking to a 8051 computer with 40k of flash running at 20mhz.

Where on earth did you find a processor running at 20 milli-hertz? Curious. I do think you mean 20 MHz. Hertz also gets capitalized because it's a proper name.
m is milli and M is mega

I'm also not sure what a Switchs is. Switches, maybe?

I use one of these ethernet switches. Not for switching a 3 phase motor, but stuff in my garage over WiFi with a WiFi add on.

As for KeepItSimpleStupid, talk about posting for posting sake....

You can always create a simple TX/RX circuit using 2 PIC microcontrollers and EUSART then write a simple computer program to comunicate with your PIC at 9600bps over RS232. The program(server) receive connections from a trigger application(client) which you can use to send a signal. Alternatively, you could create a simple PHP interface to send the control signal.

One I saw recently used nearbus and IFTTT

You would need a relay that will switch the contactor somehow or put a relay on each of the 3 phase lines
