Product Specification

Low Power Carbon Dioxide Sensor NRID CO2 Gas Sensor COZIR-A Summary
COZIR is an ultra low power (3.5mW), high performance CO2 sensor, ideally suited for battery operation and portable instruments. 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 0-2000ppm, 0-5000ppm and 0-1% the COZIR Ambient Sensor is suitable for applications such as Building Control and Horticulture.
