  author={C.‐C. Chang and Z.-F. Yang},
NDIR-based CO2 sensor is commonly used in the field of environmental monitoring due to relatively high accuracy compared with that of a chemical CO2 gas sensor. This paper presents a wireless sensing system with a low-cost Non-Dispersive InfraRed (NDIR) sensor module used to determine gas concentration in a remote air quality monitoring system. Unlike the chemical CO2 gas sensor, the proposed sensing system has new features not only for reaching high precision criteria and for enhancing long…

Development of Low Cost Crowd Sensor
Deployed sensor nodes show the potential of this system for certain application in closed room where monitoring crowd density is needed and the capability of detecting human occupancy from minimum into larger data scales is suggested.


A study on NDIR-based CO2 sensor to apply remote air quality monitoring system
Recently, various CO2 sensors reported in the literature may be classified in two major categories depending on measuring principle of sensors. Fist, the chemical CO2 gas sensors have the principal
Novel NDIR CO/sub 2/ sensor for indoor air quality monitoring
This paper describes NDIR CO/sub 2/ gas sensor with novel optical cavities and two elliptical mirrors that are optimized for the optical path and light intensity. The new structures have two distinct
The NDIR CO/sub 2/ monitor with smart interface for global networking
The NDIR (nondispersive infrared) monitor provided with a smart network interface is developed for distributed measurements of CO/sub 2/ gas concentration in the atmospheric air. Two thermopiles in a
