• Ultra-low power CO2 sensor• Ideal for battery-powered operation • Fit and forget, fully autonomous operation • Long life, >15 years About the CozIR®-A The CozIR®-A is a low-power NDIR CO2 sensor using state-of-the-art solid-state LED optical technology. The LED technology enables the CozIR®-A to reduce power consumption to levels that make it particularly useful for battery powered or wireless interface applications where power is at a premium. CozIR®-A is a universal sensor option for ambient sensing applications with an easy-to-use UART digital interface or a low impedance voltage output for CO2 measurement readings. The CozIR®-A features built-in auto-zeroing ensuring the sensor exhibits high accuracy over the lifetime of the sensor. In addition, the CozIR®-A has a number of user definable choices to optimise integration into a wide variety of environments including different mechanical mounting options and extended temperature ranges.
