Remote Evapotranspiration Sensor Package

Background
The United States Department of Agriculture (USDA) Agricultural Research Service (ARS) is seeking to acquire two portable, solar-powered plant evapotranspiration remote sensor towers. These sensors are essential for monitoring plant moisture stress and water use in real-time across multiple field experiments, as the research unit currently lacks the technology to obtain evapotranspiration values from remote sites.

The goal is to enable users to monitor plant stress effectively in various environments.

Work Details
The contract involves the delivery of two (2) portable, solar-powered plant evapotranspiration remote sensor towers with the following specifications:
1. Evapotranspiration sensor capable of monitoring plant water losses to the atmosphere.
2. Direct output of evapotranspiration measurements without requiring further calculations or additional sensors.
3. Coverage capability for at least 1 – 2 acres of field.
4. Remote deployment capability including necessary solar panel hardware (battery, charge controller, and solar panel).
5. Data logging and backup functionality without reliance on third-party software; data should be downloadable via a manual connection to a laptop.
6. A mounting structure for accurate sensor deployment within target areas.
7. Accompanying software that allows data use/download without a cloud-based subscription.
