  • Page 13: Application Scenario

    6. Application scenario In the use case of detecting the garbage in waste bin, the device should be installed on the top of the waste bin. After the device is installed and powered, turn on the device and it will detect the distance between the device and the garbage as well as the percentage of the garbage in the waste bin.
  • Page 14 Illustration 2. If the R718X is installed as the following way, then the measured distance needs to add the height of the device itself which is 28mm. Note: (1) The default value of OnDistanceThreshold is 500mm, and the default value of FillMaxDistance is 2000mm.

  • Page 18: Information About Battery Passivation

    8. Information about Battery Passivation Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high.

  • Page 19: Important Maintenance Instruction

    9. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: • Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it completely.
