Abstract:
The goal of this study was to examine a multichannel device using five commercial Non-Dispersive Infra-Red (NDIR) heads for the sensing of methane concentration changes in soil probe. The presented device consists also of a temperature and humidity sensing unit, a gas chamber equipped with a micro-fan, automated gas valves and a microcontroller that controls the measuring procedure. The temperature and humidity sensors are used to control working conditions. A redundant sensor unit is used to improve the measurement accuracy. The device worked in maintenance-free mode installed on soil probe for six hours. The main development of the proposed sensor included measurement procedures and proposition of errors corrections.
