Install before you trust the numbers
The sensing tip belongs in the root zone, in firm soil contact. A probe lying on a dry crust will decode perfectly and still be wrong. Recheck depth after cultivation.
Slow the uplink to the interval on the datasheet if you want the multi-year battery window. Faster reporting is available; it shortens service life.
Named fields
| Field | Type | Notes |
|---|---|---|
| moisture | number | Soil moisture from the sensing tip |
| ec | number | Electrical conductivity, salt/nutrient proxy |
| battery_mv | integer | Battery millivolts |
| fcnt | integer | Frame counter |
Example after decode
{
"moisture": 28.4,
"ec": 1.1,
"battery_mv": 3400,
"fcnt": 410
}Byte offsets live in the decoder file shipped with the kit. If the first uplink disagrees with this example, trust the shipment file and the factory functional-test record.

FAQ
Can one decoder cover wind and rain as well?
No. Wind and tipping-bucket rain are separate kits and separate profiles on the same application.
What does EC mean on PS-410?
Electrical conductivity at the tip. Use it to spot salt build-up. It does not replace a soil laboratory test.
Which product page has the mounting FAQ?
The PS-410 product page. This decoder page only documents the named fields.
EU868 or US915?
Both are in the standard quote. Confirm the channel plan before you ship decoders to a second region.
