Aiming at problem that traditional water quality monitoring systems can not real-time online monitoring water quality parameters

it is difficult to accurately detect dynamic changes in water quality parameters

and water quality parameters detecting errors is large

propose a WSNs-based hardwave design scheme for water quality monitoring. This system mainly through core MCU CC2530 realize design of sensor node

and using solar panels for power supply

at the same time design hardware circuit to collect temperature

p H value

and stability test is carried out on hardware circuit. At the same time

in IRA development environment

programming of sensor node and coordinator is carried out to communicate. Experimental result shows that average relative error of temperature and p H value is 3. 06 %

1. 64 % respectively

and improve monitoring precision.
