    Electrical Isolation/Surge Protection

    Now that I have my lightning detector installed I am a bit worried about damaging my computer from lightning spikes. Anybody care to share what protection they have between their computer and 1-wire network? So far I came across: 1) Tim Bitson's grounding scheme...

    HA7Net bash scripts

    Would the bash script work with the "HA4B - RS232 Isolated 1-Wire Host Adapter"? The HA4B adapter provides electrical isolation between your 1-wire network and computer. This could save the computer from lightning surges. I was looking at the adapter earlier but did not see any Linux software...

    Input Board

    What do you mean by "input board"?

    Waterproofing Temperature Sensors

    I have used "Marine Epoxy" from ACE hardware to weatherproof/protect components with good results. It cures in a couple of hours and is very durable. It is not flexible so might not be the right choice in all situations. I have used it for sealing surface mount chips soldered into a DIP...

    Solar sensor Digitemp

    "AD" is the voltage reading of the humidity sensor. It is VAD in the schematic. In order to get the current measurement you need to send the DS2438 chip a different command sequence. This is done in the Get_Current routine that was previously posted.

    Solar sensor Digitemp

    Yes I believe so... The "AD" reading is the raw voltage output from the humidity sensor. The DS2438 can read both voltage and current on separate inputs. digitemp currently only reads the voltage output. If you want to add current readout you can add a function to userial/ad26.c and then call...

    Solar sensor Digitemp

    It is pretty easy to modify the source code of digitemp to add readout of the current. In the routine "read_humidity" add: /* Read the solar radiation */ solar_rad = Get_Current(0); you have to pass the variable to the "log_humidity" function and add it to the printout...
