Abstract/Summary
This paper examines the design process and results concerning the OWL Integrations soil monitor. Disaster relief relies heavily on digital communications, especially in environments where conventional methods (e.g. Wi-Fi, cellular, fiber optics) are unusable. To help emergency services assess disaster-stricken areas, a soil monitoring system was developed using LilyGo T-Beams (ESP32), programmed with specialized firmware known as the ClusterDuck Protocol to collect data pertaining to moisture and temperature. The project is sponsored by OWL Integrations, with help from the Cal Poly Electrical Engineering (EE) Department. Results show positive prospects, with the product able to make 4 km transmissions, operate for approximately 18 hours, demonstrate IP67 weather resistance, almost measure moisture and temperature with a ±5% error margin, and establish end-to-end communication between it and a cloud network.
