How to Accurately Compare CO2 Sensor Modules

At first glance it is difficult to discern a difference between all the CO2 sensor modules available on the market. This fact makes it difficult for many and product manufacturers to select the best components for their product. In some cases, this leads to a lower quality product but in many cases, it leads to significant manufacturing waste and numerous product redesigns due to a poorly chosen CO2 sensor module. Fortunately, focusing on a few key characteristics can make it easier to accurately compare CO2 sensor modules.

The first area of focus should be size. Even the smallest modules have the same core capabilities as larger modules. While there are other variables that set them apart, size is important to consider within the design of an entire product. In most cases, it is best to select the smallest possible CO2 sensor module that meets all the requirements of the product. The smallest options available are often integrated into small sized systems such as wall pads and monitoring devices. They are also used in air conditioners, gas equipment, and building ventilation controls. Keep in mind that many models of the same size often have different voltage inputs and specifically include or exclude features such as sleep mode support.

Another area of focus should be functionality. For example, some CO2 sensor modules are designed specifically for persistent stability and temperature resistance whereas others are created for operation within less hostile environments. The more durable solutions are often favored by customers and stock raising, greenhouse, and other agriculture related fields. In most cases, more durable solutions also include automatic calibration software which makes them popular for HVAC customers. Some modules even offer 99% humidity resistance in harsh environments.

The third area to focus on when comparing CO2 sensor modules is how ble module they operate. Some modules are designed to function with an ultra small dual channel gas module which relies on the principle of non-dispersive infrared (NDIR) while others use a traditional approach to identifying gases. The benefit of the dual channel approach is it allows for the identification of multiple types of gases such as methane, CO2, ethylene, protein, and butane. This diversity in gas recognition allows the module to be used for more comprehensive applications rather than solely CO2 monitoring.

The final area to consider is the manufacturer. This is often overlooked but plays a significant role in the long-term reliability of the product being manufactured. It is critical to select a CO2 sensor module provider who has the capabilities to produce the quantity required within the requested timeframe. Additionally, they need to have a track record of successfully fulfilling orders as well as creating a reliable product. Nothing is worse than selecting a CO2 sensor module manufacturer only to realize they provide a low-quality product or consistently failed to meet deadlines. By focusing on these four areas it will be easier to accurately compare and find the best module and manufacturer for any production need.
