Abstract

Carbon dioxide (CO₂) measurement has an important role in atmosphere monitoring. Usually, two types of measurements are carried out. The first one is based on gas concentration measurement while the second involves gas exchange rate measurement between earth surface and atmosphere [1]. There are several methods which allow gas concentration measurement. However, most of them require expensive instrumentation or large devices (i.e. gas chambers). In order to precisely measure either CO₂ concentration or CO₂ exchange rate, preferably a sensors network should be used. These sensors must have small dimensions, low power consumption, and they should be cost-effective. Therefore, this creates a great demand for a robust low-power and low-cost CO₂ sensor [2,3]. As a solution, we propose a photonic sensor that can measure CO₂ concentration and also can be used to measure gas exchange by using the Eddy covariance method [1].
