Using sonar technology we measure water level

Untrasounds sensor will send echo to water and calculate distance using speed of sound.

HC-SR04 sensor is using sonar principle

Sensors will be protected by PBA cap printed 3D.

Solar panel willl power the device

Distance from sensor to water can be between 0 and 4,5 meters for normal sensors and up to 7 meters for special ones.

Location of sensor

Installation will be usualy under/on bridges over the river
