Installation
- Drill two holes on the container cover according to the location of device mounting holes.
- 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.
Besides, the device can also be fixed by two M4 mounting screws and wall plugs.
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.
- 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.
