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.
Commissioning checklist
Join with OTAA, paste the PS-410 codec, and verify moisture and EC update after the tip sits in firm root-zone soil. Record DevEUI, depth, and crop block in the commissioning pack. Avoid air gaps and dry crust contact — a perfect decode of a dry tip is still a bad measurement.
Start at the datasheet uplink interval for multi-year battery life. Faster soil polls are available on quote and shorten service intervals. Recheck tip depth after cultivation or irrigation digs.
Limits and related kits
EC is a field proxy for salts and nutrients, not a laboratory assay. Moisture units follow the datasheet; calibrate against your agronomy method if the programme requires absolute volumetric water content.
Wind (PS-450), rain (PS-460), and light (PS-420) are separate kits and separate decoders on the same LoRaWAN application. Design the farm weather pattern on the agriculture solution page; order PS-410 from its product page.
Integration notes
Paste the codec once per device profile, then clone. Map moisture and EC into irrigation rules with deadbands so small soil noise does not chatter valves. Keep battery_mv on a maintenance board with leak and weather kits from the same farm gateway.
When EC trends up after fertigation, treat it as a field signal to investigate — not an automatic fertigation cut — unless your agronomy SOP says otherwise. Cite this decoder page and the product datasheet in RFQs so integrators do not invent alternate field names.
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.
How deep should I bury the PS-410 tip?
Place the tip in the active root zone for the crop. Shallow crust placement under-reads after irrigation. Record depth so replacements match.
Does PS-410 report soil temperature?
Only if the quoted firmware exposes it. The named fields on this page are moisture, EC, battery, and frame counter unless your shipment notes otherwise.
