Catalogue excerpts

COZIR™ Ultra Low Power Carbon Dioxide Sensor COZIR is an ultra low power (3.5mW4), high performance CO2 sensor, ideally suited for battery operation and portable instruments. Based on patented IR LED and Detector technology and innovative optical designs, COZIR is the lowest power NDIR sensor available. Optional temperature and humidity sensing are available. COZIR is a third generation product from Gas Sensing Solutions Ltd – leaders in IR LED CO2 sensing. With measurement ranges of 0-5%, 0-20%, 0-60% and 0-100%, COZIR Wide Range sensors are suited for process control applications such as diving, industrial safety and automotive.  Measurement ranges from 0 to 100% Peak current only 33mA Optional Temperature and Humidity Output COZIR™ Wide Range Sensor Specifications General Performance Warm-up Time Operating Conditions Recommended Storage < 10s 0°C to 50°C (Standard) -25°C to 55°C (Extended range) 0 to 95% RH, non-condensing -30°C to +70°C CO2 Measurement Sensing Method Sample Method Measurement Range Accuracy Non Linearity Pressure Dependence Operating Pressure Range Response Time Non-dispersive infrared (NDIR) absorption Patented Gold-plated optics Patented Solid-state source and detector Diffusion 0-5%,0-20%,0-60%,0-100% ±70 ppm +/- 5% of reading1 (100% Range ±300 ppm +/-5% of reading1) < 1% of FS 0.13% of reading per mm Hg in normal atmospheric conditions. 950 mbar to 10 bar2 4 secs to 2 mins (user Configurable)3 Reading refreshed twice per second.3 Information supplied by GSS Ltd is believed to be accurate and reliable.

Dimensions and Wiring Connections 2x5 0.1" header. Pin 1 is identified on the dimensional drawing. Pin 2 should not be connected. Pins 4 and 6 do not require connection and are internally The zeroing options are for hardware zeroing (both active low). These functions can also be implemented by sending a serial command (recommended). Typical connections for digital interface are GND, 3.3V, Rx and Tx. Note that the Vh for the serial Tx line will be 3V regardless of the supply voltage. The analog (voltage) output is available only when specified. Otherwise, N/C.
