Hi people
Just hooking up my new hobbyboards UV sensor and i can’t get it to register on the one wire network. Set up i have is as follows:
USB Adapter->power injector->lightning detector->UV sensor->solar sensor
The lightning and solar sensor both work fine, but i cannot get the one wire viewer or weather display to “discover” the new sensor. I also cannot get the one wire viewer to poll the sensors correctly at all, except when i disconnect the power from the power injector.
Anybody any ideas to start troubleshooting?
Thanks
Do you a seperate power going to the UV sensor? Mine are working in this order. Lightning, Solar, UV.
Hi
Thanks for the reply. I don’t have an additional power supply only for the UV, just the power injector for the network. I previously had the order of lightning detector, solar and then UV, but decided to swap them around to check that the solar sensor was not draining all of the power, which i don’t think it is at it is at the end of the network now.
Hi,
You might want to check the jumper on each of your sensors, whether taking power from the USB or the power injector. I have all my sensors taking power from the injector only. I have the same daisy chain as Mark and it seems to be working as it should. Also, Mark, did you solve your graph issue?

Nope. The strike reading in the new 1-wire viewer is not transfering to the graphs in WD. I even updated WD lastnight to the latest build, but no change.
Sorry, relatively new to 1 wire. How would I go about checking the jumper on each of the sensors?
Ok guys, bit of an update.
I tried connecting the UV sensor on its own, via the power injector to the usb adapter, and it was still undiscoverable in the one wire viewer.
I’ve also found that when the UV sensor is connected in any way to the network, the one wire viewer cannot poll the other devices in the network, until i turn off the power injector. When the UV sensor is removed and the power injector turned back on (power reconnected) the devices can be polled again.
I’ve contacted hobbyboards to see what they say and if they can offer any support.
Hi,
Looking at the Hobby Boards web site, there are some instructions for installing. See below for one of the boards manual.
http://www.hobby-boards.com/catalog/links/uvi2-r1/UVI%20Meter%20User%20Manual.pdf
The Lightning board uses the USB power.
The Solar board has a jumper, J1. If you jumper it, the board will use the power from the Power Injector, if you remove it, the board will use the USB power.
The UV board has to have power from the power injector, therefore, you will need to have your cable so that pin 7 is the plus 12 VDC and pins 3 and/or 5 is ground or negative.
Hope that this makes some sense.

Just an update for anyone following this thread. Still in contact with HobbyBoards trying to resolve the issue. Very good support so far, sent the sensor back and was tested ok. Still not working upon return, trying to figure out why. My only guess is that the power injector could somehow not be working? However, i thought that the solar sensor relied upon this functionality, and it seems to be working fine. I also have both led’s on 5v and unregulated power lit up fine.
I’ve tried just the power injector straight to the UV device on its own, and it still cannot identify it in onewireviewer.
As always, any ideas welcome.
Hello,
I have the same issue, and too have sent the unit back to Eric, it worked fine when he got it. I have tested it on it’s own with the power injector, no joy, not seen 
I have just check the voltages on the RJ45 sockets, the unregulated is 15v and the 5v regulated is 5v.
I’m going to get the scope out later have have a look at the signals on the 1wire bus.
John
Ok, I have just looked at the bus, and it looks good, no attenuation of the signal. I can see the 1wire bus signal on the board. There seems to be a regulator on the board, not sure what it’s out put should be, but it’s at 3.3v.
I wonder if it is a driver issue, what version drivers are you using.
I’m on 4.0.3 on Windows 7 32bit.
John
I’ve tried a few drivers across different machines…
Win XP
Win 7 64 bit
Still no luck. Purchased a rain gauge also and that cannot be discovered/work…it also makes the adapter unfindable by onewireviewer when connected.
Really strange, going to get my hands on another adapter to try that out, see if its a USB adapter issue. If no, the only other 2 possible bits i haven’t checked are the power injecter and the RJ11-RJ45.
Hi,
Maybe this might be of some assistance. Check out this thread http://discourse.weather-watch.com/t/51058 for possible driver issue with the 1-Wire system.

Thanks for that, i’ve had a read.
I’ve managed to get my hands on another adapter and installed, and i’m pleased to say, ITS WORKING! 
at long last. So i guess it was the USB adapter that died and maybe would not address the new sensors.
However, one problem still remains, the rain guage is still non functioning and whenever connected it makes all the other sensors dissappear. Even when connected on its own, it makes the adapter dissappear in the one wire viewer. I think there is something wrong with the the rain guage or the wiring that is breaking the one wire circuit. Any one faced this before?
Hello!
2 weeks ago trying to get your uv sensor wire but for some reason fails.
I tried to have 2 different PC configurations. Windows 7 64 bit and Windows XP.
The weather display is replanted several times.
The power supply: 3 com (10030973) Output: 12 V = 1.5A
Power injector is ok.
Solar everything.
UV does not recognize the pc.
One wire solar senzort reader should also come to recognize the data successfully, but if after the junction of the solar uv-t it does not appear in the UV detector only if you’re in and out of connection to the USB.
Having thus turned on and off the adapter will appear in the program.
Extracted in this case, the UV sensor ID and paste it into your dallaswire Reader.
in this case should recognize the principle of UV dallaswirereader senzort!, but for some reason you can not see.
Voltage values were measured at 12 V instead of 12.18 V and 5 V instead of 4.85 Volt.
I think this is not a problem.
This is now the second uv senzorom it worked the first 2 seconds when the data was then burned. I have no idea what and why?
Please who can help?
I have also tried just about everything, still no joy
Rain gauge now working, DQ and GND wired wrong way round, just swapped them over and hey presto!
Really pleased.
JohnnyBoy, Nanasmet, have you tried changing the adapter?
Hello,
Yes, three different adapters no joy.
John
Johnny, have you tried using the onewireviewer to view the device? Could be a driver issue as you say as if you’ve tested the Cables (What cables are you using?) and the kit, have you tried a different USB/Serial port?
Hello,
Yes, used onewireviewer, changed cables, tested cables… Tried it as only device on the bus. checked out power injector, put a scope on the data line, and it does not look good!, With the controller on only, you can see data at 5vpp however with the UV sensor plugged in nothing, 0v… with a little noise. I think the device is dead, however Eric tested it and told me it was fine!
I feel I will just throw it in the bin, and forget having a UV sensor.
