| [13:10:57] | <cpm> | So, how was the show? |
| [13:24:14] | <mstenta[m]> | cpm: it was great! |
| [13:24:26] | <mstenta[m]> | lots of people were drawn towards the table by blinky lights on little circuit boards :-) |
| [13:24:41] | <mstenta[m]> | (in case you didn't see the pics already: https://www.instagram.com/p/BgM807VB3Th/) |
| [13:26:13] | <cpm> | blinky lights are hard to beat. |
| [13:27:17] | <cpm> | just a fwiw, I'm pretty sure the soil temp/hum sensors die when submerged for very long. |
| [13:27:35] | <cpm> | don't know what to do about that. |
| [13:28:29] | <mstenta[m]> | Yea I think @donblair:matrix.org you experienced that problem too? |
| [13:33:38] | <cpm> | I *think* that the sensor sitting in contact with damp soil is enough to kill it. Was meaning to (later this spring) sacrifice *another* one by putting 2 down, one enclosed in a screen, like a tea-ball so the soil can't contact the shield directly, buried next to a regular one, see how closely they track each other. See which one fails. |
| [13:35:47] | <sdutcher> | How about this type? https://www.adafruit.com/product/1298 |
| [13:36:36] | <cpm> | yeah, I've got 3 of those left. |
| [13:36:40] | <cpm> | still in the pouch. |
| [13:36:51] | <cpm> | I've killed my other ones. :) |
| [13:37:08] | <sdutcher> | So no good huh |
| [13:38:18] | <cpm> | Ummm, , some folks seem to make good use of those. But some of us have reliability issues with them. I'm not sure of the base cause. They just stop working after a while. I *think* they don't like getting flooded. |
| [13:38:50] | <cpm> | if the soil is at field capacity, the actual sensor could get wet. |
| [13:38:53] | <mstenta[m]> | Yea I think that's what @donblair:matrix.org was testing too |
| [13:39:13] | <cpm> | if the soil is actually flooded, then it will certainly get wet after a day or so. |
| [13:39:24] | <sdutcher> | I can see that |
| [13:39:49] | <sdutcher> | That mesh wont stop water totally |
| [13:40:13] | <cpm> | why I'm thinking placing it in a tea-ball or something, so that the housing doesn't actually touch the soil might help. |
| [13:40:34] | <cpm> | unless flooded. But at field capacity, should still not get submerged. |
| [13:40:54] | <sdutcher> | That would be a good cheap solution |
| [13:41:00] | <cpm> | else, going to have to come up with a goretex-y-ish shield of some kind. |
| [13:41:30] | <cpm> | but I don't trust membranes for humidity |
| [13:42:09] | <cpm> | the actual ht10 ic itself seems to be pretty ubiquitous. |
| [13:45:46] | <sdutcher> | What's the point of failure on those sensors? It must the HT10 because the rest of the board looks to be conformally coated. |
| [14:09:24] | <cpm> | I don't know. |
| [14:09:50] | <cpm> | but I also suspect the ht10 itself. |
| [14:19:33] | <cpm> | would help to know what kind of humidity sensor the thing is. |
| [14:20:18] | <cpm> | I assume thermal |
