PS-450

PS-450 Wind Payload Decoder

The PS-450 decoder publishes wind speed, gust, and direction for farm weather poles. Record boom height so year-over-year comparisons stay valid.

Field contract

After decode, dashboards should show speed, gust, direction, battery, and frame counter. Keep the cup/vane clear of guy wires and solar panels.

Rain and soil kits join the same application with their own profiles — never paste wind fields onto a tipping bucket.

Named fields

Example after decode

{
  "wind_speed": 4.2,
  "wind_gust": 7.1,
  "wind_dir_deg": 245,
  "battery_mv": 3360,
  "fcnt": 119
}

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

Why document boom height?

Wind speed depends on height. Without it, seasonal comparisons are meaningless.

Same codec as rain?

No. Tipping-bucket rain uses the PS-460 profile.

Icing?

Ice on cups stalls speed while fcnt still moves. Inspect after storms.

Bands?

EU868 and US915 standard. Confirm other plans on the quote.
