Grain Quality Sensor
C02 Monitoring
OPI’s CO2 sensors monitor carbon dioxide levels to provide an early indicator of active grain spoilage caused by biological activity from molds and insects.
- Proactive Loss Mitigation: Alerts users to potential issues in their early stages, allowing for immediate action to prevent or minimize grain loss.
- Comprehensive Coverage: Specifically designed to be installed in the storage headspace and plenum, increasing sensor coverage in grain storage.
- Enhanced Visibility: Complements standard temperature and moisture cables to help provide a deeper layer of grain data.

C02 is an early indicator of activity that can damage your grain.
Did You Know?
Normal background CO2 is 400 – 600 ppm.
OPI Grain Quality Sensors have 50 ppm accuracy up to 2000 ppm.
Complements a comprehensive monitoring and control system with cables.
Why is carbon dioxide monitoring useful when managing grain in storage?
Given that CO2 moves with air currents much faster than heat conducts in grain, CO2 sensing overcomes the limitations of temperature cables and can give a more “real-time” indicator of the onset of grain spoilage.
I already have cables to monitor my grain in storage. Why should I add Grain Quality CO2 sensing?
Peace of mind while storing your grain comes from having complete visibility of the grain condition and quality. To achieve this level of visibility, a storage facility should supplement the temperature and moisture cables with CO2 sensors. By having both temperature and moisture cables along with CO2 sensing, you will have the most comprehensive data set available. This enables not only early detection of spoilage from the CO2 data, but also critical information, like the grain temperature and moisture, ensuring your grain is in optimal condition when it is time to sell.
Where are the Grain Quality Sensors Installed for optimal CO2 readings?
For a monitoring only cable based system, the Grain Quality Sensor would be installed on the storage structure roof with the sensor protruding down into the headspace above the grain. The Grain Quality Sensor would be connected into an updated Cable Node. If you have an automated fan control system, the Grain Quality Sensor would be installed in the plenum and connected into an updated Fan Node. To achieve the most comprehensive CO2 monitoring, an additional Grain Quality Sensor should be added to the headspace of your storage.
