Wireless monitoring for agriculture

By monitoring key conditions agricultural businesses can check soil properties variances, machine behaviours, aquatic conditions, climate conditions, atmospheric physics and more.

By monitoring these conditions Agribusiness can:

  • 1 Increase food quality
  • 2 Increase operations efficiencies
  • 3 Increase machinery life cycles
  • 4 Realise ideals and standards associated with precision agriculture.

By the year 2050 world growers expected to produce 70% more food.

Agribusiness is an ever evolving industry.

It is predicted there will be a millennium shift from family operations to smart food factories.

By employing automation technology means operations can keep pace with Agribusiness trends.

What is precision agriculture?

Precision agriculture is defined as the optimisation of farm land for maximum profitability and yield, while sustaining a stewardship of farm lands and public safety, through observing and measuring crop health.

To understand the perspective, the same farm acreage that was expected to feed 26 people in 1960 will be expected to feed 265 people by the year 2050.

Agriculture consumption of water is approximately up to 85% of the nations water consumption. This places substantial financial pressures on farmers to maximise the efficiency of water consumption.

Rural crime

The very nature of an agricultural organisation often means their livelihood is achieved in rural locations, and sometimes even ‘off grid’.

There is considerable investment made in vehicles and machinery too. Being rural brings with it its own complications. Agricultural crime covers working farms, farm machinery, farm buildings and smallholdings.

Offences include theft of equipment or fuel, damage to property and to livestock. Often offenders know they are unlikely to be caught by police as there is usually a considerable delay in crime agencies attending rural crime scenes.

Agriculture sensing

The opportunities for wireless sensing in agriculture are innumerable and obviously depends on which areas of agriculture are being farmed.

A report published by the Broadband Commission for Sustainable Development identifies a plethora of sensor solutions that have track records saving money in areas such as crop production, food storage, distributions, air monitoring and soil monitoring (temperature, salinity, PF and water levels).

By monitoring these conduits allows growers to leverage sensor data and increase yields and efficiency. Routine readings of humidity levels, water levels, temperatures, door positions and other variables translate to saved assets, protected resources and avert disasters.

Typical sensors for agriculture

Light monitoring

VIGIL+ wireless light meters measure the intensity of light from 0–83,000 LUX (luminescence/unit area), plus an optional detection reading of light/no light. By default, the detection reading is triggered on LUX value being above or below the configured minimum threshold value of the sensor.

The Wireless Light Meter uses a highly sensitive photo-diode to detect and measure the intensity of light around the device. The sensor is also capable of alerting upon detection of a change in lighting conditions.

Quantity of light

Plants use light as a source of energy for photosynthesis. The term photosynthesis refers to the reaction between carbon dioxide and water in the presence of light to produce carbohydrates and oxygen. The rate of this process is highly dependent on the light quantity; the photosynthesis rate is higher as the Photosynthetic Active Radiation (PAR) increases. The carbohydrates produced during photosynthesis are stored and used by the plant as a food source. Each plant species starts the process of photosynthesis at different light energy levels, which is called the light compensation point. This point starts when light energy is sufficient for photosynthetic activity to produce more oxygen than is required by the plant for respiration.

Rate of photosynthesis

Likewise, the release of carbon dioxide through respiration by the plant must be less than the total carbon dioxide used by the plant for photosynthesis. In other words, the net photosynthesis is zero:

Net Photosynthesis = Photosynthesis – Respiration

Light saturation point. More light generally equates to higher levels of photosynthesis. However as the light intensity increases, the photosynthetic rate eventually reaches a maximum point. This point where the light intensity does not increase the photosynthesis rate is called the light saturation point. When this point is reached, the photosynthesis rate curve becomes flat.


VIGIL+ wireless temperature sensors come in a few options. Ambient temperature sensors are compact and sealed in the body of the sensor. Whereas there are temperature probe options that are available with a lead cable of differing lengths. Caution: The temperature sensors are not water proof so for areas that require water resistance either select a sensor in a water proof housing or consider the VIGIL+ thermo coupler option.

Thermo coupler

VIGIL+ wireless thermocouple sensors are available with a hardwired thermocouple or K-type connector to support various thermocouple types and ranges.

The hardwired thermocouple option measures temperatures up to 400°C (752°F).

The K-type connector with Probe includes a needle probe that measures temperatures up to 400°C (752°F). Thermo-couplers are water and weather proof so if there is a requirement to measure temperature in moist or wet areas or in soil thermo-couplers should be used.

Thermocoupler monitoring


VIGIL+ wireless humidity sensors measure the Relative Humidity (RH) in an area. RH is a crucial factor when growing pants in greenhouses or poly tunnels.

RH that is too high interferes with plant transpiration. It also causes condensate droplets on the ceiling and walls which reflect light. This can reduce the amount of light transmission into the greenhouse for plant growth.

Too little RH also can stress plants by accelerating transpiration to more than what the roots can take up and translocate. The solution to these and other humidity concerns is a program of systematic humidity management.

Humidity monitoring


VIGIL+ wireless water sensors alert detect when there is water present, preventing potential property damage that results from flooding or leaks. Place this sensor anywhere flooding or faulty plumbing could cause a problem. This sensor can also be used to detect a lack of water, allowing you to know when a container is nearly empty.

An optional spot detection probe can be added to the end of the water detection wire. The spot detection probe can be positioned and mounted at a set distance above the ground eliminating false alarms.


VIGIL+ wireless Co2 sensors measure the amount of Co2 in an area. Studies have shown that higher concentrations of atmospheric carbon dioxide affect crops in two important ways: they boost crop yields by increasing the rate of photosynthesis, which spurs growth, and they reduce the amount of water crops lose through transpiration.

Plants transpire through their leaves, which contain tiny pores called stomata that open and collect carbon dioxide molecules for photosynthesis. During that process they release water vapour.

As carbon dioxide concentrations increase, the pores don't open as wide, resulting in lower levels of transpiration by plants and therefore increased water-use efficiency.

CO2 monitoring


VIGIL+ wireless open/closed sensors provide information on the status of doors, windows, cabinets, etc.

Knowing if doors or windows are open is an important feature.

Cabinets that contain secure items or tools may also need to be monitored.

Open/Closed monitoring

Liquid Level

VIGIL+ wireless liquid level sensors use a solid state, continuous (multi-level) fluid level sensor for measuring levels in water, non-corrosive water based liquids and dry fluids (powders).

Water level monitoring


VIGIL+ wireless motion sensor is ideal for detecting if unwanted guests are present. Infrared motion detectors can prove a useful guard agains theft and damage. VIGIL+’s wireless motion sensors use an infrared sensing technology to accurately detect movements made by people or even animals such as rats and other vermin.

As Vigil+ motion sensors use infrared they are non-obtrusive and can be installed in confined areas without attention being drawn to their use.

Motion detection monitoring


VIGIL+ wireless CO sensors are ideal to detect early warnings of carbon monoxide. Carbon monoxide poisoning is a real threat to confined or restricted areas that have machinery in use. Any area that have fire or combustibles present are also a potential dangerous generator of Carbon Monoxide.

Agricultural buildings often have machinery running inside them such as mills, saws, forges etc… They are also likely to have paraffin heaters or log burners in areas where people work. Monitoring the CO in these areas is vital to ensuring the safety of workers and staff.

CO monitoring

Dry Contact

VIGIL+ wireless dry contact sensors detect when there is contact between two wired end points.

They can easily be integrated into existing switches or contact plates.

The sensor can be configured to detect both closed and open loops alerting if contact is made or broken making them ideal to monitor for open gates and hatches on farmland.
