The CozIR®-LP2 5000pp CO2 Sensor holds the lowest power and longest lifespan of an infrared CO2 sensor available today, with I2C interface.

The GC-0034 or CozIR®-LP2 5000ppm CO2 Sensor prides itself on low power consumption which makes it easily integrated into battery-powered systems, including smart technology devices and IoT applications.

Designed around measuring low levels of carbon dioxide, the miniature, ultra lightweight GC-0034 can be utilized in many gas monitoring and detection systems.


  • Measures up to 1% CO2 concentration
  • Solid-state, no moving parts, no heated filaments
  • Vibration and shock resistant, non-heating
  • Digital (UART) and I2C Output
  • Up to 50X lower power than typical NDIR CO2 Sensors
  • Compact size, for easy instrumentation integration
  • Long lifespan, low maintenance
  • Ideal for wireless, portable, wearable and self-powered systems
  • Supports energy-efficient smart home environments
  • Easily integrates into applications such as IAQ, HVAC, Agriculture, MAP, Automotive, Aerospace, and Safety.


CM-20141 COZIR LP2 Development Kit  Simply plug the USB cable into your Windows 7-10 PC and download our free GasLab® software to measure, graph, and log carbon dioxide data.

CM-20140 - COZIR LP2 5000ppm CO2 Sensor on Board – Same functionality as the development kit without USB cable or software.

GC-0034 COZIR LP2 5000ppm CO2 Sensor – designed for low concentration CO2 environments with measurement ranges from 0-2000 ppm, 0-5000 ppm and 0-1%.
