Salinity measurement and control device measure conductivity in desalinated seawater and calculate salinity.Compare measured salinity values with the default alarm salinity values
and control changes of status indicator and on/off of relay
so realize alarm and control of seawater desalination system.The equipment consists of STC12 series MCU
sensors
and driver peripheral circuits.The measured values of salinity sensor are affected by temperature
so it needs temperature compensation.A few kinds of algorithm are analyzed by Matlab
and the optimal compensation algorithm is found and programmed into MCU system
