1. 01

   The whole FarmMast

   One solar mast head reads the buds, the sky, the dew point, the trough and the trap, wakes its night camera when an animal comes, and sends it all over one LoRa link.

2. 02Brain

   ESP32-P4NRW32X

   The brain: it runs the farmmast-fw program

3. 

   03

   Bud, sky and dew sensors

   Bud temperature on the branch, clear or cloudy sky, air and dew point for the frost and sprinkler alerts

   ESP32-P4NRW32X · I²C (shield cable for the SHT45) · Bud, sky, air °C and humidity, every minute

4. 

   04

   Night camera and IR LEDs

   Names the animal at the gap at night

   ESP32-P4NRW32X · MIPI CSI-2 ribbon · A short burst of stills per wake

5. 

   05

   Three motion sensors

   Wake the brain when a warm animal walks into the gap

   ESP32-P4NRW32X · 3 wake lines (GPIO) · Motion on front, left or right

6. 

   06

   Trap camera

   Photographs the sticky liner in your delta trap and counts new moths

   ESP32-P4NRW32X · DVP camera bus on a 200 mm ribbon · Up to 6 photos a day

7. 07

   Trough pod and meter

   Water level and temperature at the trough, inflow from the pulse meter on the float-valve line

   ESP32-P4NRW32X · 15 m cable: UART, 1-Wire and the meter's pulse line · Level, °C and litres in

8. 08

   Strobe and siren driver

   Fires a random light and sound pattern only when an animal is there

   ESP32-P4NRW32X · 2 GPIO to the MOSFET board, 12 V from the boost · Pattern on and off

9. 

   09

   LoRa radio

   Sends every job to the farm gateway and rings the RaidBell and FrostBell

   ESP32-P4NRW32X · UART (AT commands) · One packed message per event

    All connected

    8 key parts, one program, and your phone

The idea

One solar mast where the orchard meets the paddock: bud frost, the stock trough, raiders at the gap and the moth trap

How the parts connect

FarmMast, wired up

Every part, what links it to the brain, and how the data reaches your phone. A solid line is a cable; a dashed line is a radio link.

The program

What controls FarmMast

void app_main(void) {
  Wake w = wake_cause();                    // LP core or a PIR
  if (w == WAKE_PIR) {
    Animal a = classify(raidcam_burst());     // RaidPost
    if (a.kind != PERSON && a.kind != ELEPHANT) deter_fire(random_pattern());
    lora_send_now(event(a));                  // rings the RaidBell
  }
  Climate c = lp_shared.climate;              // FrostMast
  if (frost_risk(c, bud_stage())) lora_send_now(frost(c));
  Trough t = trough_state(lp_shared.level, lp_shared.pulses); // TroughTally
  if (t.fault) lora_send_now(t);
  if (due(TRAP)) store(new_moths(trapcam_still())); // TrapTop
  if (due(MORNING)) lora_send(summary());
  lp_core_run(sleep_loop); esp_deep_sleep_start();
}

Pricing

Target pricing. Bought separately, FrostMast ($249 per head), TroughTally ($199 per trough + $36/yr), RaidPost ($145 per post) and TrapTop ($129 + $29 per season) add up to $722 + about $65 a year. Parts cost about $376 per mast at qty 10 (est.), the meter alone $76.

Indicative launch pricing in USD, excluding taxes and shipping. Final pricing is confirmed before any balance is charged.

1. 28 Oct 2026, 16:55LatestA mixed farm where an orchard block meets a paddock needs frost at the buds, the stock trough, animals at the field gap and moth counts watched together; today that is a $389 to $1,252 frost alarm, a A$749 to A$1,290 trough monitor and a trap camera near $2,700, each on its own post (Onset, fruitweb, Farmbot and iScout listings, sources in DESIGN.md).

   • Drawn idea plan (idea.json): a field corner from above with the end rows of an apple block, the maize field, the hedge gap that boar and deer use, the paddock with its trough and the farmhouse up the track; pins for the mast at the corner, the trough pod and the frost and raid bells in the house
   • The product picture is now this drawn plan instead of the plain fallback card; drawn from the rev A design notes, not the CAD
   • What we kept from the market work: no product we found does frost, trough, deterrent and trap counting on one mast, so the plan shows all four jobs from one spot and names the limit that the trough must sit within about 15 m of the corner
   • Next: drawn plans for more catalogue products that still show the fallback card

2. 27 Oct 2026, 05:10A mixed farm with an orchard next to its stock paddock pays for a frost alarm, a trough monitor, a crop-raid flasher and a pest-trap camera, each with its own pole, power and app. Commercial versions cost about $389–1,252 for a frost alarm (Onset, fruitweb), A$749–1,290 for a trough monitor (Farmbot) and about $2,700 for a trap camera (iScout, Perennia).

   • New product FarmMast: one ESP32-P4 on a solar mast does the jobs of FrostMast, TroughTally, RaidPost and TrapTop
   • New CAD parts: mast case (camera, IR, PIR windows and a tilted bud-IR boss), lid with beacon base and sky window, pole saddle, frost shield, trap arm with camera snout, 6 W panel mount, and a chipless trough pod with lid; every bought part fits and each part is one solid
   • 3D view: a field corner with the mast beside the end apple tree, the delta trap under the arm, the paddock fence and the trough with the pod on its rim
   • Dropped: two XIAO brains and their radios, all AA cells, TroughTally's chip at the trough, TrapTop's bucket gate; WinterWatch, ColdSpot and DewSpot stay separate add-ons
   • Product page https://iemilabs.com/products/farmmast/: $499 + $39/year instead of $722 + about $65/year for the four; parts about $376 (est.)
