YO Distance is a LoRaWAN device for ultrasonic distance measurement. An example of using this device is monitoring the water level in the tank. Additionally, the device contains sensors that measure temperature and relative humidity.

YO Distance is equipped with an enclosure made of ASA with IP67 protection class. The enclosure is designed to be easily mounted on the ceiling, e.g. water tanks.

The device does not require external power supply.

YO Distance communicates wirelessly over LoRaWAN. We are a member of the LoRa Alliance, which is responsible for data transmission security.
