AI Technical Summary
Existing water leakage detection sensors suffer from a decrease in reaction rate and reduced supply voltage and current due to electrochemical reactions after the water battery comes into contact with water, which fails to meet the sensor's operating requirements and affects the detection effect.
A boost circuit is used to increase the output voltage of the water battery, and the energy is stored in an energy storage unit. A controllable switch is used to control the release of the energy to ensure the stable operation of the communication module.
It extends the effective working time of the sensor, improves the effect of leak detection, and can work continuously for about 4 days in a normal water environment, supporting 100-200 detection cycles.
