iDOL 139 LoRa Humidity, Temperature and CO2 Sensor

Smart 3‑in‑1 Environmental Sensor

Benefits

• Prevent CO₂ buildup for healthier animals and better air quality
• Eliminate sensor damage during high‑pressure cleaning
• Reduce mortality through accurate environmental monitoring
• Collect valuable data for management and optimization

Save Time and Money With One Sensor

Because the DOL 139 measures humidity, temperature, and CO₂, it replaces multiple individual sensors. This means:

• Easier installation

• Less maintenance

• Lower overall cost

• Fewer components to manage

One sensor, three critical measurements.

Built for Harsh Environments

The DOL 139 is engineered for long life in tough conditions commonly found in livestock houses and industrial facilities.

Withstands High‑Pressure Cleaning

• Protected by a robust casing

• Equipped with a specialized filter

• Includes a protective cap for washing and disinfection

• Safe even during high‑pressure cleaning routines

Easy Upgrade and Replacement

The DOL 139 is designed to seamlessly replace:

• DOL 19 or DOL 119 CO₂ sensors

• DOL 104 humidity sensors

• DOL 114 humidity and temperature sensors

Once installed, the DOL 139 becomes the single sensor needed to measure humidity, temperature, and CO₂ — simplifying your entire monitoring setup.

Built-in LoRaWAN Converter for wireless communication

The sensor has a built-in LoRaWAN converter that sends data wirelessly to the iDOL 64 LoRa gateway.

Power cable included

A 2-meter power cable for 24 VDC is included but we also offer an external power supply used for supplying 80-240 VAC and a 2-meter cable with M12 plug and sealing plug for wired connection to the gateway.
