The TreeTag

At just 3.5” long and a few ounces, the TreeTag is a compact sensor delivering real-time insights into crop water status and environmental conditions. Its dendrometer directly measures tree growth to detect water stress, while accelerometer, temperature, and humidity sensors provide additional context. Powered by a solar panel and hybrid capacitor, the TreeTag sustains itself for over a decade, even under dense canopies. Data is wirelessly transmitted to a gateway up to 1 km away, making it ideal for orchards and vineyards of any scale.

TreeTag Data

Each TreeTag is equipped with a dendrometer to measure radial growth, offering direct insights into plant health and water status. By combining this with accelerometer, temperature, and humidity readings, the system collects a detailed view of plant responses to environmental and irrigation conditions. The system processes these measurements into a Water Stress Index and delivers actionable recommendations through the API, enabling smarter irrigation.

The Data Portal

The Data Portal offers convenient functionality to get started with dendrometry data and manage your TreeTags. View a detailed list of your devices, organize them into custom groups, and monitor connectivity and battery strength. Built-in tools allow users to graph and compare datasets, track irrigation impacts, and export historical data for deeper analysis or integration into third-party platforms.

Installation and Maintenance

Installing a TreeTag takes less than 90 seconds. Each device mounts securely with a single screw into a trunk or branch and is activated using the ePlant app (no service required). Once installed, TreeTags operate autonomously, requiring only occasional reseating—typically once every one to two years, depending on growth rate. As the trunk expands, the dendrometer’s range decreases until it bottoms out, a change tracked in the data and predictable in advance.

The ePlant App

The ePlant app streamlines deployment and in-field management of TreeTags. With a simple NFC “Tap,” the app activates each device, logs its GPS location, and verifies connectivity—all without requiring a cellular connection. Users can then check live sensor readings, confirm LoRa connectivity, and control data collection through an intuitive interface. Regular updates ensure compatibility and add new decision-support features over time.

Networking

TreeTags use LoRaWAN to transmit data reliably up to 1 km. They can connect to existing LoRaWAN infrastructure or to ePlant’s pre-configured gateways for out-of-the-box connectivity. Configurable to support any regional LoRaWAN standard, the system is deployable worldwide. Even in the event of connectivity outages, TreeTags store up to 8 years of data for uninterrupted records.

The Gateway

TreeTags connect to any standard LoRaWAN network, but ePlant offers pre-configured indoor and outdoor gateways that guarantee seamless operation. These gateways require power and an internet connection via Ethernet or cellular backhaul. Each gateway supports thousands of TreeTags, facilitating reliable and efficient communication in a variety of deployment environments.

Designed for Tree & Vines

TreeTags are purpose-built for agriculture, mounting securely to trees and woody vines with trunks or branches over 1.0” (2.5 cm) in diameter. This ensures precise dendrometer readings and stable installations without harming crops. Their versatility makes them ideal for orchards, vineyards, and other perennial crop where irrigation precision drives productivity.
