Intelligent micro-control system for water sensor and control method of intelligent micro-control system

The invention discloses an intelligent micro-control system for a water sensor and a control method of the intelligent micro-control system. A micro-control unit of the intelligent micro-control system comprises a calibration module, a monitoring module, a correction module and an alarm module. After the water sensor is immersed in constant-temperature water and the electrodes at the two ends of the detection mechanism are in contact with the water, the micro-control unit provides constant-value voltage, so that an electrified loop is formed between the electrodes at the two ends, the monitoring module measures return current in a power supply access of the water sensor, and a corresponding relation between a safety margin value and the return current is established through the calibration module. An alarm current threshold value is determined, and an alarm module sends out a water immersion signal; when the electrodes at the two ends are corroded, the loop resistance is increased, the return current value me
