Feature

●The kit outputs the depth value through the serial port, is compatible with 5V and 3.3V control systems
●Water depth sensor can be easily connected to the ready-made control system for use.
●The module has its own calibration data storage function, which stores calibration data values ??and will not be lost when power is turned off.
●The higher the water level, the greater the water pressure, resulting in the greater the inductance of the inductor coil in the sensor
●The higher the water level, the greater the water pressure, resulting in the greater the inductance of the inductor coil in the sensor, and then according to the parallel resonance frequency formula of the inductor and capacitor
