2.2 Installation
To ensure correct operation and reliable and consistent level measurements, install the EGK-
LW20W00 sensor on the lid interior. Screws are provided. The device measures the distance to the
closest target on its field of view. It works with different waste materials like organic, glass, paper,
plastic, residual waste.
The measure is performed periodically according to parameter Period [min].

2.3 Power ON/OFF
The sensor is shipped completely off to prevent battery consumption during storage. It is therefore
necessary to carry out a first power-on prior to commissioning.
To power on the sensor: lay the magnet at the bottom of the provided tool into the area shown in the
figure:

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
Successful power on is signaled by the flashing of the 3 LEDs.
In case of long period of inactivity, if necessary, is possible to shut-off again the sensor to prevent
battery consumption, via downlink or with LoRa Tool App:

Place the front panel and fix it with the 4 screws.
After the batteries replacement, internal counters need to be resetted.
To perform the operation, you need a unique reset code that must be requested to enginko (please
provide the DevEUI of the sensor when you ask for that code):

At the end of the procedure the battery level displays 100%.
2.6 Firmware update
Save the firmware file (.FW) on the smartphone, and upload it with LoraTool App:
3. Measures
On each reading of the sensor by LoraTool, the measured distance is shown on the main page:

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
The temperature value is measured inside the sensor.
Once provisioned on a LoRaWAN® network, the device sends the distance, temperature, filling level
& timestamp to the server via uplink.
3.1 Level settings
Level measurements are carried out according to few parameter settings. A target over the defined
range cannot be detected. Read and write of parameters can be done using LoRaTool App. They have
a default value and can be modified to be tailored on the specific use case.
Meaning of parameters is related to following diagram. The “REFERENCE” (distance=0mm) is the top
surface of the sensor:

3.1.1 Start [mm]
Starting point of the measurement (in mm from “REFERENCE” point).
Values can be set from 140 to 1360:

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
Default: 140
A target within the “Start [mm]” distance will result at a “Start” distance.
The “Start [mm]” value is also related to other level parameters. Contact enginko in case of
assistance.
3.1.2 Lenght [mm]
Range of measure (in mm, from “Start” point).
Values can be set from 0 to (1500 - “Start [mm]”):
