Abstract
Sagebrush are an integral part of the ecosystem in the western United States that are often damaged by wildfires and other stressors. Reseeding efforts often yield poor long-term success. It is hypothesized that understanding how sagebrush use volatile organic compounds (VOCs) to communicate could improve reseeding efforts. This project aims to provide a wireless method for collecting spatial-temporal VOC data in the field. Detecting VOCs is done with a laser induced graphene (LIG) sensor which changes its equivalent resistance in the presence of VOCs. This sensor is integrated with a Wheatstone bridge and amplifier circuit to convert the resistance change into a voltage that can be sampled. This sensor is then combined with other basic sensors, like temperature, humidity, and soil moisture, to create a sensor tag system that communicates its data wirelessly. This approach allows for large-scale deployment of many sensor tags that can together monitor a large population of sagebrush.
