  2. Put the device under container cover and align the holes in order to perfectly screw the bolts into the holes from the other side of the cover.

Milesight-EM400-MUD-Multi-Functional-Ultrasonic-Distance-Sensor-image (25)

Besides, the device can also be fixed by two M4 mounting screws and wall plugs.

Milesight-EM400-MUD-Multi-Functional-Ultrasonic-Distance-Sensor-image (26)

Installation location

  • In order to provide the best data transmission, please ensure the device is deployed within the signal range of the LoRaWAN® gateway or base station and keep it away from metal objects and obstacles.
  • The device must be placed in a horizontal position above the detected object so that it has a clear path to the object.
  • The device should be installed at least 30cm away from the side-wall without obstructions blocking the ultrasonic signal. If the device needs to be installed on the side wall, please ensure the ultrasonic horn is away from the side wall.

Milesight-EM400-MUD-Multi-Functional-Ultrasonic-Distance-Sensor-image (27)

  • When EM400-MUD is in waste bin mode, place the device in the center of waste bin mode and here are some recommended sizes of waste bins: when the height is 88cm, the minimum radius should be 24cm.
