Well depth (cm) - to the bottom:



The well depth value is calibrated to calculate the actual level. If the value is 0, the results are inverted. The level from the sensor at the top of the well is determined. More water = less distance from the sensor. (The result is a lower water level).

Well diameter (cm)




Maximum depth of well with diameter 160 cm (for successful measurements with an ultrasonic sensor without reflections from the walls of the well):


Estimate - HC-SR04 Ultrazvukový senzor vzdialenosti - hladinomer Arduino: 597.13 cm

Estimate - JSN-SR04T Vodotesný ultrazvukový senzor vzdialenosti - hladinomer Arduino: 92.38 cm

Measurable range: 450 cm

Limited by sensor.
