We demonstrate low-power, integrated laser-based tracegas chemical sensor systems which directly interface to the Telos wireless sensor networking (WSN) modules. We will demonstrate a prototype sensor which measures atmospheric oxygen concentration configured as a battery powered, handheld unit with power consumption ≪0.3W, sensitivity of 0.07%, high specificity, and the robustness required for long term environmental sensing applications.
