K8055 to "1 wire" temperature sensor network?

Hi
I am thinking of buying the K8055

The outputs are 50v 100ma max - could i drive relays from this? they would be switching 230v ac 5amps

I have searched for relays but havn’t found any yet.

I have one other question if you don’t mind.
I wish to wire in the inputs to a “1 wire” temperature sensor network do you think this would work, I would use the pc to read the network (if i can find the or write software ?)
it’s a very long time since i did any electronics and nothing like this stuff, so am a bit unsure of myself.

any advice would be appreciated

They need microsecond scale timing. The K8055 can change the output state once every 10ms.

Thanks very much thats helped a lot.

What would be the best interface to my PC? do I have to have a micro controller Board?

I dont really want to get into programming micro controllers - I am pretty proficient in C# and VB.net But i’m not sure how to go about it?

Thanks again

Mike

The Velleman K8067 Universal Temperature Sensor is designed to use together with the K8055/VM110.

(Also exists assembled and tested: VM132)

If you like to use the 1-wire temperature sensor connected to the PC, you can use Google to find a lot of applications and hardware: This search: “1-wire temperature sensor” “PC” gave for instance this link:

Thankyou :slight_smile:

Its funny, I have been googling for days on the 1 wire network but never came up with those two!
