Smart Irrigation

Overview

Pyro-E’s energy harvesting technology allows small, standalone sensors to function continuously for extended periods of time — decades, even — without battery replacements. This technology greatly enhances the  capability of low-power sensors and mitigate the need for maintenance as a solution for autonomous sensing, diagnostic, and control. The drop-in replacement hardware resembles a pressure regulating valve and can harvests energy from hydrostatic pressure fluctuations. The latter occurs across minute, hour, and daily bases, which can be harnessed for electricity to power remote monitoring devices. For leak detection, any abnormal pressure drops or fluctuations would suggest the likely event of a main break in the local distribution network. 

Pyro-E was selected as a Finalist to The Water Council's Spring 2020 Tech Challenge!

Highlights of the innovation:

 

•  Power capability spanning three orders of magnitude from 0.1 to 100 milliwatts for battery replacement

•  Frequency-matched response to low-duty pressure fluctuations less than 0.01 Hz

•  Pressure-matched response to small pressure fluctuations +/- 2 psi

•  Passive self-start power management circuitry with 82% input-output efficiency

•  Power generation independent of frequency and quadratic to pressure input.

Key user advantages:

• Powered by pressure transients as low as +/- 2 psi

• Operational without flow or fluid contact

• Zero battery replacement for 10+ years
