System and method for underground wireless sensor communication

This invention describes a system for monitoring conditions beneath the ground using a network of sensor devices. Some sensors are fully buried, others partially exposed, and each is powered and communicates wirelessly. They gather information about sub-surface material characteristics, sending it to a central hub for storage, which a separate control unit then retrieves and displays.

Why it matters: Since 2021, advancements in low-power wide-area network (LPWAN) technologies have made long-term, energy-efficient wireless communication from remote and underground sensors more viable. Additionally, improvements in battery technology and energy harvesting could extend the operational life of buried nodes.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateWireless sensor nodes, rugged enclosures, data gateway.
