Optimum Animal Welfare

Maintaining the right climate is one of the most critical factors in efficient pig production. Pigs are highly sensitive to changes in temperature, humidity, and air quality. Any imbalance can lead to heat stress, poor feed conversion, increased disease risk, and reduced growth rates. Automated climate and ventilation systems are transforming how farmers manage these challenges — ensuring healthier animals, greater efficiency, and higher profits.

The Importance of Climate Control in Pig Housing

Optimal climate control directly influences animal welfare and performance. Pigs cannot sweat, so managing heat and humidity within their environment is essential. Poor air quality caused by excess ammonia, carbon dioxide, or dust can also impact respiratory health and feed intake. Manual monitoring and adjustments can be time-consuming and inconsistent, especially in large-scale operations.

Automated systems solve this by continuously monitoring environmental factors such as:

• Temperature and humidity levels
• Ammonia and carbon dioxide concentrations
• Airflow and ventilation rates
• External weather conditions

By automatically adjusting fans, heaters, and inlets, these systems keep conditions stable around the clock.

Livestock production has always depended on experience.

Whether managing a poultry house or a pig facility, experienced producers develop a strong understanding of animal behavior, environmental conditions, and daily operations. These insights are built over years of observation and hands-on management.

As monitoring technologies become more common in modern livestock production, some producers wonder whether data is replacing experience.

The reality is quite the opposite.

Experience Still Matters Most

No sensor can replace the knowledge that comes from working with animals every day.

Experienced producers can often spot subtle changes in behavior, identify unusual patterns, and recognize early signs of developing challenges before they become serious problems. That expertise remains one of the most valuable resources on any farm. However, even the most experienced manager cannot be everywhere at once.

The Need for Greater Visibility

Modern poultry and pig production is becoming increasingly complex.

Environmental conditions can change throughout the day, often without obvious signs. Ventilation performance, temperature, humidity, CO₂ levels, and water consumption may shift gradually before they become noticeable during routine inspections. This is where continuous monitoring adds value.

Rather than replacing human expertise, monitoring technologies provide an additional layer of visibility that helps producers better understand what is happening inside the house or barn.

Better Information Supports Better Decisions

Reliable data helps producers make decisions based on facts rather than assumptions.

For example, the DOL 119 CO₂ Sensor provides insight into ventilation performance and indoor air quality, while the DOL 114 Humidity & Temperature Sensor helps monitor environmental conditions that influence animal welfare and productivity.

For producers seeking a broader environmental overview, the DOL 139 combines temperature, humidity, and CO₂ monitoring in a single sensor.

Production indicators are just as important. The DOL 90 Water Meter continuously monitors water consumption, often one of the earliest signs that something within the livestock house has changed. Together, these measurements provide valuable information that supports daily management decisions.

Sensors for Livestock

dol-sensors innovates, designs, and produces intelligent livestock monitoring sensors for agriculture and other industries.

Our product range contains capacitive sensors and climate sensors.

All of our sensors for livestock are specially designed for lasting a lifetime and to withstand the harsh environment in livestock houses.

What Are Livestock Sensors?

Livestock sensors are devices designed to monitor and gather data related to the environment in the barn and feed supply and consumption. They can be seen as the nexus where technology meets livestock management, providing farmers and farm managers with a detailed insight that was previously inaccessible or hard to obtain.

The primary drive behind the development of these sensors was the increasing need for real-time, accurate data to optimize farming operations. Traditionally, farmers and farm managers relied on periodic checks, intuition, sense of smell, or visible signs to assess the health and productivity of their livestock. However, such methods are often reactive rather than proactive. With sensors, farmers can now detect potential issues before they escalate, ensuring timely intervention and reducing losses.
