DOL 139 (140283) 3 in 1 Temperature & Humidity & CO2 Sensor FAQs

What does a DOL climate sensor measure?

DOL climate sensors measure environmental conditions such as temperature, humidity, ammonia (NH₃), CO₂, and air pressure to support proper ventilation and climate control in livestock buildings.

Why are climate sensors important in animal housing?

They ensure optimal living conditions for animals. Good temperature, humidity, and air quality help improve growth, reduce stress, and maintain animal health.

How are DOL climate sensors installed?

They are generally mounted on walls, ceilings, or climate stations where airflow is stable. They must be placed away from direct water spray, heating sources, animals and drafts to give accurate readings.

Do DOL climate sensors require servicing?

Most sensors require periodic servicing—typically once per year—to maintain accuracy. This is ensuring the sensor is clean. Gas sensors like ammonia require a replacement sensor cartridge after 3 years or CO₂ may need more frequent checks depending on use.

Can climate sensors work with automatic ventilation systems?

Yes. DOL climate sensors are designed to connect with climate controllers. The controller reads the sensor data and automatically adjusts fans, heaters, and cooling systems to keep the environment stable. A variety of control systems can be catered for including 0-10v, 4-20Ma and 0-5v
