  • Low power CO₂ sensor
  • Solid state LED optical technology
  • Vibration and shock resistant
  • UART data interface
  • Built-in auto-calibration


Some CO₂ sensing applications require exposure to harsh environments, from extreme pressure and extended temperature to an unstable environment with sudden shocks and vibration.

The ExplorIR® NDIR CO₂ Sensor range is built to endure extreme changes in the environment such as pressure and temperature. You can measure both low and high levels of CO₂, from 0-100%. The NDIR CO₂ sensor is shock resistant meaning they can provide an accurate reading in unstable environments. With the ExplorIR® range of CO₂ sensors there is no compromise on power consumption and are the ideal solution for battery power applications.

The ExplorIR® range of CO₂ sensors is based on our SprintIR® technology platform, bringing the benefits of solid state electronics to NDIR CO₂ sensors. ExplorIR® CO₂ sensor uses LEDs to deliver ultra-low power and rugged/vibration-resistant performance to the industrial platform, delivering a sensor capable of measuring 100% CO₂ concentrations with ease.

In continuous operation ExplorIR® NDIR CO₂ sensor delivers two samples/second and consumes only 3.5mW in continuous operation. Even with two carbon dioxide measurements per second delivering low latency and accurate results, it is typically 50 times lower powered than standard NDIR sensors.

The combination of extremely low power consumption and instantaneous warm-up of the ExplorIR® NDIR CO₂ sensor, answers directly the growing demand for sensors which can be integrated into battery or self powered wireless systems, allowing economical real time monitoring of CO₂ concentration levels.

In addition, the small 20mm diameter of the ExplorIR® sensor makes it the ideal sensor for use in probe, portable and battery powered applications.
