Measure CO2 with ExplorIR-W sensor

ExplorIR®-W (formerly known as CozIR Wide Range) is a high concentration, low power CO2 sensor, with optional temperature and RH% sensing, and optional analogue (voltage) output. The sensor is built to reliably measure CO2 levels in harsh environments, up to 100% concentration. This includes applications exposed to varying degrees of pressure and high vibration conditions.

Its low power requirement also makes it ideal for battery powered systems, including portable, wearable and self-powered applications as it only requires 3.3 v. The sensor is easy to use as it communicates via a simple UART Interface.

ExplorIR®-W CO2 sensor is built on our unique patented LED technology platform and optical designs. It’s this solid-state CO2 monitoring technology that enables best-in-class power consumption, lifetime and durability.
