Livestock and dairy

Livestock and dairy, with the herd’s conditions on record.

Healthy animals need clean air, water, feed and a climate they can bear. Barn gas and climate sensors, water meters, cameras and pasture water points report to one record the farmer, the vet and the inspector can all read, and the emissions record follows from the same measurements.

  1. Agriculture · Livestock and dairy

    The herd cannot tell you

    Animals in a house depend on fans, water lines and heaters that can fail in the night. A broken drinker or a stalled fan is noticed late, and illness shows first as a change in how much the animals drink. Measuring the air, the climate and the water in every house catches these early.

  2. What is measured

    Air, climate, water and the animals

    Gas sensors read ammonia and carbon dioxide at animal height; climate sensors read temperature and humidity inside and out; meters count water on every supply and level sensors watch pasture troughs. Cameras let the farmer check the animals the moment an alarm sounds.

  3. The base node

    A farm node that keeps watch

    An industrial gateway reads the barn sensors and the ventilation controllers over their own buses and hands them to the farm node, which signs every value. The node raises ventilation, heat stress and water alarms at once and keeps the camera clip around each alarm.

  4. Radio and links

    Barn wireless, paddock LoRaWAN

    Inside, the farm’s wireless network carries cameras and gateways without trenching through concrete. Out in the paddocks, LoRaWAN carries trough levels from places with no power. The farm reaches the office, the vet and the processor over cellular, with a buffer for outages.

  5. How it works

    From a dry drinker to a call

    A water meter on a house supply stops counting. The gateway passes the reading to the farm node, which sees the flow fall against the herd’s normal pattern, raises the alarm with a camera clip and calls the stockperson. The record keeps the reading, the alarm and the repair.

  6. From order to operation · Order

    Scope the houses, the herd and the permit

    The scope reads the farm layout, the herd, the ventilation and water systems, the welfare duties and any emissions permit. Nexus Observatory Inc. returns the point plan by house and paddock, the network design, the integration with herd software and a price per house and per service.

    Plan a deployment
  7. From order to operation · Survey

    Walk the barns with the stockperson

    Crews walk every house with the stockperson to find representative points at animal height, away from direct airflow and out of reach of the animals. They check wireless coverage in the barns, LoRaWAN coverage to paddock water points, and where cameras can see pens without blind corners.

  8. From order to operation · Permits

    Biosecurity, privacy and permits

    Crews follow the farm’s biosecurity rules on every visit. Cameras that see staff are covered by a written notice and a data policy. For permitted pig and poultry units, the measurement plan is agreed with the permit holder so it matches what the permit requires.

  9. From order to operation · Build

    Build for dust and ammonia

    Gas, climate and water sensors are chosen for corrosive, dusty air, built into sealed enclosures and tested with the gateway and node. Each is enrolled with its identity, configured for its house and alarm limits from the farm’s welfare plan. Every part is labelled for quick replacement.

    Open the Station Builder
  10. From order to operation · Install

    Install between batches

    Where possible, installation happens between batches when houses are empty and clean. Sensors are mounted at animal height, water meters fitted on each supply, cameras aimed over pens and alleys, and pasture water points mounted on troughs. Every point is photographed for the record.

  11. From order to operation · Commission

    Test every alarm

    Each device proves its identity. Gas sensors are checked with a reference gas, climate sensors against a reference, water meters against a measured volume. Ventilation, heat stress and water failure alarms are triggered on purpose and reach the farmer and, where agreed, the vet.

  12. From order to operation · Operate

    Care for the herd on evidence

    The farmer sees air, climate and water in every house and paddock, with alarms when something fails and camera clips to check animals at once. Water use and climate trends flag illness early, and the emissions record follows from the same measurements, ready for inventories and permits.

  13. From order to operation · Maintain

    Clean, check and replace

    Gas sensors are checked with reference gas on schedule and replaced at the end of their life, enclosures are cleaned during house washing, and water meters are checked yearly. Every change is recorded against the point, so welfare and emissions series stay consistent.

  14. Data products

    For farmers, vets and inspectors

    Farmers receive house dashboards and alarms; vets receive early health signals and clips; processors and sustainability teams receive emissions inventories; inspectors and permit authorities receive welfare and emissions records. Each product carries the measurements, the calibration and the siting behind it.

    See the data products
  15. Evidence

    Welfare and emissions on one record

    Every reading, alarm, response and calibration is signed and kept with its time and place. Welfare duties follow the protection of farm animals rules and animal health codes, emissions follow IPCC inventory methods and, for permitted units, the best available techniques, so any inspector can check them.

01The place and its hazards

Where it runs, and what can go wrong.

Operating contextDairy, beef, pig, poultry and sheep farms keep animals housed, on pasture or both. Welfare rules set duties for air, water, feed and care; large pig and poultry units hold environmental permits with ammonia limits; and herd health depends on catching heat stress, water failures and illness early. Barns are dusty, humid and corrosive for electronics.

Hazards

  • Ammonia and dust in housed livestock
  • Heat stress in hot, humid weather
  • Water supply failures in barns and on pasture
  • Disease spreading before it is noticed
  • Corrosive, dusty air that shortens sensor life

02What must be measured

What, where, how often, and under which rules.

05From order to operation

Every step, from the first call to a running site.

The same crew and the same record carry the work from scope to maintenance.

  1. 01 Order

    Scope the houses, the herd and the permit

    The scope reads the farm layout, the herd, the ventilation and water systems, the welfare duties and any emissions permit. Nexus Observatory Inc. returns the point plan by house and paddock, the network design, the integration with herd software and a price per house and per service. 26

    Walk the barns with the stockperson

    Crews walk every house with the stockperson to find representative points at animal height, away from direct airflow and out of reach of the animals. They check wireless coverage in the barns, LoRaWAN coverage to paddock water points, and where cameras can see pens without blind corners.

07Questions buyers ask

Before you scope it.

Do sensors survive barn air?

They are chosen for ammonia and dust, sealed, cleaned during house washing and replaced on plan.

Will the system control our ventilation?

No. It reads the controller and raises alarms; the controller and the farmer stay in charge.

Who sees the cameras?

The farm decides. Staff are told in writing, and footage is kept only around alarms unless the farm chooses otherwise.

Does this help with our emissions permit?

It measures what the permit asks for and keeps the record; the permit holder reports it.
