1-Wire HVAC monitoring system

1-wire hvac control

The 1-Wire HVAC monitoring system is for residential Geothermal HVAC systems. This project utilizes the so called 1-wire temperature sensor. A single board computer handles the brunt of the work including web accessible trend data. With access to the underling temperatures, the over all system performance may be gauged. Earlier this year we covered a HVAC web enabled monitor that adds an element of control. As the industry adopts modern control architectures, we hope to see more HVAC hacks around.

  1. ourcoolhouse inspired me to use 1wire in my attic cooling. cool house indeed

    This is nothing really new. In fact people have been using the One-Wire parts with the software for Linux based systems to manage their whole houses since about three to four years back. (Perhaps longer, when did the hacked Wireless router from Linksys come out wearing a pair of serial ports?)

  3. very nice information. This project utilizes the so called 1-wire temperature sensor. A single board computer handles the brunt of the work including web accessible trend data.

    cool stuff.

    i hate how its called 1-wire

    its not one wire, its 2 wires

    @anon: hate all you want. it only uses one wire if both ends have access to a shared ground. one wire from the standpoint of your microcontroller.

    get over it

    about how much did you spend overall (controller and temp sensors)? I want to do this

    Very cool, and way less expensive than the commercial/proprietary monitoring/energy management systems on the market today

    Nice. Now for external wind speed, direction, and anythings you can think of monitoring. How do I hook up to a USB port,and hub?

    naming it 1-wire probably for marketing..
