Hi Eric, can you tell me how long the lead wires are on the soil moisture sensors please? Can you also tell me whether the wires can be extended, and if so, to what length and with what kind of cable/wire? Assuming the wires can be extended to a reasonable length, then I think I'd probably...

Hi, is anyone using 1-wire technology to measure the water level in a pond (with fish) ? I have seen a couple of ways, one using capacitance and one using IR, both with a DS2423. Has anyone here tried one or both ? Regards Dave

Hi, does anyone know the maximum frequency that a DS2423 could reliably accumulate counts for please ? Also, at what value does the counter "roll-over" ? regards Dave

Louie, this is not going to be much help if you're 180 miles away......but I'd suggest a failed humidity sensor. I got the same (10.23) volt reading from a new T/H sensor and returned it for replacement. Eric did not have time to do much testing, but we agreed that the humidity sensor was...

Hi Mitch, thanks for the reply and the pointer to the problem. I'm a bit relucatant to poke around the surface mounted chips but the sensor is U/S as it is. Eric has agreed to repair/replace, so apart from the inconvenience of sending it back to the US (from the UK) I think that's what I'll do...

Eric, thanks for the info, I'll use cat 6 I think (as the rest of the network is) and go with the 1m that you suggest. Just need to plan exactly how I can best locate the T/H sensor in relation to the S. Mike, thanks too - just wish I had the "problems" associated with mounting the sensor in...

Hi Eric, thanks for the reply. I would like to change the code to work in mBar so, yes please, if you could find the formula to use for the Barometer I'd appreciate. No hurry, though, I'll use a conversion factor in the short term, regards Dave

Eric, I'm reaching the same conclusion - the solar sensor needs to be mounted off the T/H board. Do you have any feel for how far away the solar sensor could be extended, using say cat5, from the board ? regards Dave

Hi, when I ordered the barometer, I never specified that I'd prefer metric units (mbar) for pressure so the slope and offset values are based on inHg as is the data on the calculation page on the HB site. I know that I can just convert the inHg value but would it be better to specify...

Hi, as some of you may have noticed, I'm trying to get some T/H/S working. I'm still struggling a little with the code, but I'm seeing some strange effects that some of you may be able to help with please . . . . . I'm reading one T/H/S and one T/H sensor and get the following output from my...

OOoopps - sorry folks not sure what happened here but I was trying to post this to the Maxim support boards regards Dave

Hi, I'm aware that the Battery BU don't monitor this list so I'm not expecting any Maxim support on this question. However, the question seems to have come up a number of times so perhaps one of the users on here has solved the problem and would like to share the resolution ? The "C"PD Kit...

Peter, I'm looking at the same thing at the moment - just figuring out what to do with my code to make it work. What I can tell you though is that the Solar sensor is not a separate 1 wire chip. The DS2438 Battery Monitor in the HB H/T/S sensor is used to read the values from the Humidity AND...

Hi, I'm using some home grown software based on Digitemp which has support for Humidity but not Solar. I am just about to modify the code to add in the Solar and came across the helpful posts by "pbarp". Rather than reinventing the wheel, I plan on cribbing that code. Before I start messing...
