Durable and Immersible Network Enabled Ammonia Sensor for Water Monitoring

Stanford researchers have designed an ammonia sensor for water monitoring that is low cost, durable, immersible, and integrated into a cloud network. Capable of detecting down to 0.01 ppm, these sensors can be deployed in rivers, wastewater and possibly ocean waters for real-time, remote monitoring. By using chemically resistant platforms and a low power draw design, these sensors protect against fouling, which allows for longer immersion times and minimal field maintenance.

This technology is part of a portfolio of related inventions (S19-331, S20-348, S20-349, S23-336) that extracts value from wastewater by reclaiming ammonia from nitrate-contaminated wastewater streams.
