Geolux LX-80-AB water level sensor uses radar technology to provide a precise contactless measurement of the distance from the sensor to the water level. This functionality is achieved by transmitting a frequency-modulated electromagnetic (radio) wave in the 80 GHz frequency range (W band) and measuring the frequency shift between the transmitted wave and the electromagnetic wave reflected from the water surface.

The radar sensor can be flown in autonomous mode at an altitude of 30-40 meters along the river and provides water surface elevation profiles with centimeter accuracy. Because water is an excellent reflector of microwaves, the radar return will be dominated by water targets. If there are any water surfaces within the footprint of the sensor, those will dominate the return signal.

Typical applications:

• Water level monitoring for rivers, channels, and lakes
• Water reservoir monitoring and irrigation control
  
• Observing the level of various fluids in the chemical industry
• Monitoring levels in wastewater, industrial applications

Kit includes:

• Geolux LX-80-AB radar level sensor
• Cable to connect the sensor to onboard computer
• Gimbal and mountings
• Software for sensor data logging

Kit requires the onboard computer to log the data.

Datasheet:

integration allows the sensor to be used with various drones, including DJI M350/M300 RTK, and Pixhawk-based drones.

Geolux LX-80-AB is an "airborne" version of sensor.
