dol-sensors is specialized in agriculture and thus understands your daily work routines and struggles. We constantly improve our sensors to make your daily work easier, as it is our mission to contribute to global efficient and sustainable food production.
To make your daily work easier, our sensors have features like:
To trim a capacitive sensor, you will need to adjust the sensor’s sensitivity so that it is better suited to the specific application in which it is being used.
Our capacitive sensors can be trimmed by using a standard screw driver or the SmartAdjust App on your Smartphone. The sensitivity and the delay length of the DOL 40 Series are adjusted by two switches. LEDs indicate when the switches are activated, to make it easier for you to complete the trimming.
Many of our sensors are IP67-rated, making them waterproof and dustproof.
Some of our sensors (e.g., the DOL 119 CO2 sensor and the DOL 139 humidity, temperature, and CO2 sensor) are equipped with a protective cap that allows them to withstand high-pressure cleaning. This eliminates the need to remove the sensor when cleaning animal housing.
No more damaged sensors during cleaning!
In environments where temperature fluctuations and high humidity pose a challenge to sensor reliability, the DOL 44 Capacitive Relay Sensor stands out as a robust solution. This advanced sensor features an integrated heating element, specifically designed to prevent condensation and ice buildup — a common problem in very cold or damp settings that can impair sensor accuracy and longevity.
Capacitive sensors operate by detecting changes in capacitance caused by the presence of materials, making them ideal for monitoring levels of grain, feed, and solids. However, in environments with condensation and cold temperatures, moisture and ice can interfere with sensor readings. The DOL 44 counters this issue by maintaining a stable internal temperature, ensuring consistent performance regardless of external conditions.
The built-in heating function not only increases the reliability of the sensor but also extends its operational life in demanding agricultural, industrial, or outdoor applications.
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.
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.
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.

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.
The SmartAdjust App helps you control all your sensors’ functions in an intuitive way using only your smartphone.
SmartAdjust works with all iDOL sensors and gives you precise adjustments without having to remove the sensors.
With the SmartAdjust App you can copy settings to multiple sensors and thus adjust all your sensors at once prior to installation. There is no need for powering the sensors before adjusting them with the app.
You can also save configuration setting for later or share them with others.
The app makes it possible to do more with one sensor. For example, you can configure your iDOL sensors to have on/off delay and Max Run Time at the same time.
