Conventional experimental setup for tunable diode laser spectroscopy employing vertical cavity surface emitting laser (VCSEL) operating near 1300 nm was utilized for measurements in laboratory conditions. Characteristic spectral features of ammonia, hydrogen fluoride and methane were found in the tuning range of available VCSEL diode, implying feasibility of the given technique for construction of sensor nodes. Implementation of such units into the wireless sensor networks and early warning systems for risk areas and industrial sites is therefore presumed. This work summarizes some aspects concerning NIR-TDLAS measurement technique, sensor node construction and presents innovative concept of designing the sensor network, data handling and interpretation.
