The CozIR®-LP2 (formerly known as the GC-0034) holds the lowest power and longest lifespan of an infrared CO2 sensor available today, with an I2C interface.

This 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 CozIR®-LP2 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.
