Wireless and Low-Power Water Quality Monitoring Beat Sensors For Agri and Acqua-Culture IoT Applications

摘要

This paper presents water quality monitoring IoT Beat Sensors. The interval times of ID code transmitted wirelessly from Beat Sensor nodes correspond to amount of salinity, water levels, and pH, so that receivers can acquire these parameters from many sensor nodes in agriculture and aquaculture fields. In experiments, this system can measure salinity in range 0.58%~6.48% with average power consumption of 500uW, water level in range 3.5~10.5cm with average power consumption of 90 uW and pH in range 3.45~9.58 with average power consumption of 70 uW.
