The awiss wireless sensor helps detect bacteria e.coli in water

Researcher Jeffrey Talley, working at Johns Hopkins University, USA, and colleagues from the Combination of Solutions for Environmental Technology USA and Corps of Engineers US has successfully created: Sensors The AWISS is capable of rapidly detecting and measuring the concentration of E. coli bacteria present in water samples.

The results of this study were published in the journal Environmental Engineering Science.

Because of the presence of the E. coli gut bacteria, it produces an enzymatic reaction that increases the fluorescence intensity in the water sample. The battery-operated, wireless optical sensor (AWISS) can quickly detect and measure changes in fluorescence intensity in a water sample. The presence of high concentrations of E. coli in water samples will be detected in less than an hour; Low E. coli concentrations will also be detected in less than 8 hours.

The AWISS will conduct an analysis of each water sample within 6 hours to detect and detect E. coli, and then send the results to the monitoring stations. from far away.

Methods for detecting Escherichia coli bacteria (presence of E. coli in water samples that indicate faecal contamination of water samples) currently only produce results in 24 to 48 hours.
