Product Specification

Carbon Dioxide Sensor NDIR CO2 Sensor COZIR-W Summary
COZIR is an ultra low power (3.5mW), high performance CO2 sensor,ideally suited for battery operation, portable instruments and HVAC. Based on GSS IR LED and Detector technology, and innovative optical designs, the COZIR offers the lowest power NDIR sensor available.Optional temperature, humidity and light sensing are available. COZIR is a third generation product from GSS - leaders in IR LED CO2 sensing.

With measurement ranges of 0-5%, 0-10%, 0-60% and 0-100%, COZIR Wide Range sensors are suited for process control applications such as diving, industrial safety and automotive.

    • Ultra-low Power 3.5mW
    • Measurement ranges from 0 % to 100%
    • 3.3V supply. 
    • Peak current only 33mA.
    • Optional Temperature and Humidity Output
