ExplorIR®-W CO2 Sensor

Gas Sensing Solutions' ExplorIR-W is a robust, low power CO2 sensor with analog (voltage) output. The sensor is built to reliably measure CO2 levels in harsh environments. This includes applications exposed to varying degrees of pressure and high vibration conditions.

Its low power requirement makes it ideal for battery-powered systems, including portable, wearable, and self-powered applications. The ExplorIR-W CO2 sensor is built using the unique patented LED technology platform and optical designs from GSS. It is this solid-state technology that enables some of the best power consumption, lifetime, and durability in its class.

ExplorIR-W is available in measurement ranges 0 to 20% concentration. The sensor is suitable for a range of process control and similar demanding applications. It can be used for battery applications where low power consumption is required. This includes IoT applications, such as wearables.
