An intelligent underwater depth estimator exploiting COTS underwater pressure sensors. The filter takes in pressure and temperature from the sensor (and timestamps from an RTC) and uses an alpha-beta filter to calculate the depth of the object, with built-in thermocline, noise and timestamping error compensation.
Can be used in embedded devices in real-time. Example sensor includes MS5837-30BA underwater pressure sensor, which can measure both pressure and temperature underwater. Timestamps can be obtained from real-time-clock modules or supplied from the microcontroller.

Example cpp code:
#include "mbed.h"
#include "platform/mbed_thread.h"
#include "depth_filter.h"
depth_filter_class my_filt;
float arr[3];
int main()
{
while(1)
{
my_filt.d_filt(10.2, 0.0, 2.3, 23.5, 34.7, 2.5, 0.3, 0.2, 0.2, arr);
printf("%f",arr[2]);
}
}
