Gas Sensing Solutions have a lot of experience when it comes to agriculture and CO2 monitoring. So, when a major player in this industry was looking for a carbon dioxide sensor to use in their device, we were more than happy to accommodate.

Grain is a very valuable asset to farmers, as it is only harvested once. Should something happen to this yield, the farmer will need to wait until he can harvest again, causing great economic losses for the business.

After harvest, grain is typically stored in silos. While in the past, these were tall structures of up to 90ft, today it is more common to find silo bags being used over the traditional tower silo.  These long plastic bags can vary in length, depending on the stock it is holding. Due to the low capital investment required for silo bags, they are particularly popular in the developing world. They are also much easier to move grain into than the tower silos.

There are many factors which can cause grain to spoil throughout the year. These include temperature, moisture and infestation of both insects and mould. Should the grain come into any contact with the above, the grain will become unsellable and cost the business greatly. Much like a tower silo, the silo bag still carries these risks.

One way to protect the grain against wastage is to monitor the levels of carbon dioxide it gives off. By tracking the levels of CO2, farmers can detect a change in the crop, as spoiling grain gives off a higher level of carbon dioxide compared to good quality grain. These levels are then tracked over a period of time using carbon dioxide sensors to take multiple readings within the storage unit and feedback a reading.

Our customer chose to use the ExplorIR-W CO2 sensor within their carbon dioxide monitor, as it offered the end user many advantages over other sensors on the market. Firstly, the ExplorIR-W sensor features optional temperature and humidity sensors, in addition to the CO2 sensor the customer was looking for. The monitor humidity to determine if there is the presence of a biological process that may contribute to grain spoilage.

Secondly, like all GSS carbon dioxide sensors, the ExplorIR-W CO2 sensor is low power. The sensor therefor can be fitted inside the silo, and not require a battery change during the entire season. This in turn saves the farmer both time and money.

The ability to monitor CO2 levels is useful for farmers, as they can manage their stock wisely and should a problem arise, they can deal with it in a timely manner, thus minimising the extent of damage to their yield.

Our customer chose to use our sensor in their monitor due to the low power capability is possesses. As the monitor would need to stay inside the silo bag until it was ready to be emptied, the ExplorIR-W meant this would be possible.
