Ultrasonic LoRaWAN
Installation Guide
Thank you for purchasing the Tekelek Ultrasonic LoRaWAN waste bin
sensor which uses ultrasonic technology to measure the contents of your
waste bin and then communicates this data to a LoRaWAN network.
STEP 1: Activation
The Ultrasonic LoRaWAN waste bin sensor works in conjunction with a
LoRaWAN network and a connected platform and before activation must
first be registered with both. Access to the LoRaWAN backend server is
required to verify that the unit has correctly joined the network. See User
Manual for further details.
Ensure that the LoRaWAN™ network is within
communication range of the
sensor. This should occur before the sensor is physically fitted onto the
Tank.
Place the sensor as close as possible to the point of installation,
press the button for 1 second to connect to the LoRaWAN
network and upload a status message.
The LED will stay illuminated as the sensor registers:
Red
LED flashing = The sensor is registering & connecting for the first
time. (Sensor is shipped in dormant state).
Green
LED flashing = The sensor is already registered. The
connection process will take between 20 & 40 seconds.
After the connection has completed, the LED will
flash on & off (to indicate whether the connection
was a success or failure).
LED Patterns
Press and hold the button for approximately 1 second, until the LED
turns green.
Wait approximately 10-20 seconds and observe if the LED flashes
green or red.
See the following for description of Green/Red LED flash codes.
LED Radio Signal Strength Flash Codes:
LED Pattern
Function
Green
X 3 Flashes
Excellent signal strength
Green
X 2 Flashes
Good signal strength
Green
X 1 Flash
Adequate signal strength
Alternate
Green
/
Red
Flash
Weak signal strength
Weak signal strength: Try 5 times and if this response is stable then
it’s deemed adequate. If the sensor shows some double red flashes
during this signal strength test - then an external antenna should be
tried. It may need to be elevated for best performance.
LED Error Flash Codes:
LED Pattern

Red
X 1 Flash

X 2 Flashes
No response from LoRaWAN network
Red
X 3 Flashes
General Error. Please try again. If the
error persists, contact the supplier for
support.
Red
X 5 Flashes
Maximum number of allowed button
presses exceeded (up to 6 button
presses per hour allowed).
STEP 2: Installation
The following outlines the Ultrasonic LoRaWAN waste bin sensor
mounting options.
The sensor is to be fitted on the underside (inside) of the top of
the waste bin.
The sensor must sit in a vertical position and be fitted such that
the sensor has a clear path to the tank contents. Position it so
that it is as close to the centre of the bin as possible and ensure
there are no internal obstructions that may interfere with the
ultrasonic signal.
Once a suitable position has been located, fix the sensor in place
by attaching the bracket to the waste bin using the bolt provided.
The antenna can be mounted on glass, metallic and plastic
surfaces.
The antenna RF cable is fed via the through hole mount base to
ensure no cable is visible when fixed and the rubber seal around
the base protects against water ingress.
The antenna is fixed via its 22mm length screw thread and can fit
onto panels of up to 13mm thickness.
