PS-410

PS-410 Soil Moisture Payload Decoder

The PS-410 decoder exposes soil moisture and electrical conductivity so an irrigation app can schedule water without parsing hex. EC is a field proxy for salts, not a lab assay.

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.

  "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.
