Imagine a low-cost IOT device measuring Free Ammonia (NH3) from 20 Parts Per Billion along with other key parameters. Ion-selective electrodes (ISE) have been a cornerstone of analytical chemistry for over a century, but persistent challenges such as the need for constant ionic strength and susceptibility to chemical interferences have limited their efficacy. In particular, the dynamic nature of environments like rivers and estuary, with fluctuating ionic compositions, underscores the limitations of traditional ion selective electrodes. In response to these challenges, optical sensing emerged in the 1960s as a promising alternative. However, conventional optical sensors, reliant on measuring intensity, suffer from similar drift and inaccuracies, requiring frequent device-based recalibration to maintain reliability. Enter Seneye's groundbreaking miniaturised optical sensor engine, offering a revolutionary spectrometry-based multi parameter solution with doesn’t suffer from interference like ION selective technologies. The patented multiplexing optical engine allows multiple chemical sensor dOts to be read through a single calibration free sensor disk. By employing sophisticated mathematics to interpret changes, Seneye's technology significantly reducing the impact of biofouling-induced drift—a common infield issue with conventional sensors. Real-time edge processing further enhances the system's robustness by monitoring for interference and deviations from known colour responses, enabling a reading confidence to be reported. This proactive approach, based on understanding the status of each sensor data point, facilitates a future maintenance-on-demand model, optimising device efficiency and reducing cost. Seneye's innovative optical sensor technology represents a paradigm shift in environmental monitoring, offering accurate, real-time data with reduced susceptibility to environmental interferences. By overcoming the limitations of traditional ion-selective electrodes and conventional optical sensors, through a fully integrated cost-effective solution this technology promises to revolutionise environmental monitoring across diverse monitoring applications. In conclusion, Seneye's spectrometry-based optical sensor engine highlights the transformative potential of novel techniques in providing accurate, real-time data in complex environmental contexts. As the world continues to confront pressing environmental challenges and regulatory pressures, Seneye's innovation offers an invaluable tool for monitoring and safeguarding our rivers at scale.
