  Abstract

In this paper, a portable high efficiency nondispersive infrared(NDIR) CO₂ sensor module with a smart device interface is developed. For low power consumption design, an IR LED was used instead of tungsten lamp for light source and an optical waveguide optimized to the sensor module is designed. With the smart device interface, power of the sensor module is applied from the battery of smart phone. The measured data of the sensor module such as CO₂ concentration, temperature, and humidity are displayed on the smart phone using android application. From measured results, the developed sensor module shows ±60ppm tolerance error from 0 to 3,000ppm CO₂ concentration range among -10°C and 50°C ranges.
