Why is important to know the CO2 level of a grain silo

 There are essentially two main reasons why you need to install a C02 sensor at the headspace of your storage facility if you want to minimize the spoilage.

First of all, it is a common and wrong belief thinking that the temperature sensor is enough to prevent damages to the crops. Many studies have shown that the temperature sensors alone are not enough to protect the stored crops. If a hotspot occurs away from the temperature cable and there is no CO2 sensor, it will be hard to detect the problem early and send warnings. Once the temperature rises and is detected by the sensor, in the worst case scenario,  it will be too late to prevent the damage and your crops will be spoiled. So, if you want to protect your crops, assure the quality and the quantity of your harvest and prevent any damages, you need a CO2 sensor installed at the headspace of your storage facility. 

Another reason why you need a C02 sensor is because a rise in the C02 might be caused by insects and molds present in the storage facility. Because they breathe,  insects and molds are responsible for releasing C02 into the stored crops. If a C02 sensor is installed at the headspace of the storage facility, the alarm will go on once the C02 raises upon a certain level, allowing you to take the right actions to prevent spoil in your storage.
