Description
ELT Ultrasonic distance sensor can be placed in various environments to
measure distance as well as temperature, humidity, and atmospheric pressure. It
is enclosed in an IP67 box and is designed to be mounted outside. ELT
Ultrasonic is the ideal sensor for measuring in advanced places or extreme
weather conditions, and has the capacity of measuring with remarkably long
range. This is a battery-powered device equipped with NFC (Near Field
Communication) and can easily be configured from a smartphone.
The barcode contains DevEUI and sensor type. This label is located at the back

Installation
1. Remove the front lid of the sensor by removing the four screws.
2. Install the battery. The ELT Ultrasonic requires one AA battery. The
battery type is 3.6V Lithium Battery (ER14505).
Caution: Using batteries other than the ones provided may result in loss of performance
and battery life, and also damage to the device. Dispose of properly, observing
environmental protection rules.
3. Close the lid and tighten the screws carefully. Make sure that the cable
gland and antenna connection is tightened to prevent ingress of
moisture.
4. Mount the device by using the two holes on the sides.

Sensor configuration
All sensor settings can be configured via a smartphone application with NFC
(Near Field Communication) or over the air via the network server and downlink
data to the sensor. The sampling rate, spreading factor, encryption keys, port,
and modes can be changed. All sensor settings can be locked from the server or
NFC to make end-users unable to read or change settings on the sensor.
NFC Configuration
1. Download ELSYS “Sensor Settings” application from Google Play or App
Store (from iOS 13) and install it on a smartphone or tablet. The device
must support NFC.
2. Enable NFC on the device and start the application.
3. Place your device on top of the NFC antenna on the sensor.
4. Remove the device. Current settings will be displayed in the application.
5. Choose “Distance sensor Maxbotix” under External Configuration.
6. Use the application to change any settings if needed.
7. Quickly tap the device on top of the NFC antenna to give the new settings
to the sensor. Make sure that the application confirms your new settings.
8. Wait for the sensor to reboot (5 sec), indicated by the LED flashing. Sensor
settings have been updated.
See the section “Help” in the application for more information.

Over the air configuration
All settings may be configured over the air via your LoRaWAN® infrastructure.
Please visit the support section on our webpage for more information regarding
downlink protocol.
Application parameters
All parameters for the “Sensor settings” application can be found in our settings
document. Please visit the support section on our webpage for more information.
Sensor behavior
NFC Read / Write
1. When reading or writing NFC
configuration data to the sensor, it starts
a timer and delays its action 5 seconds.
2. After the delay, the sensor determines if
the NFC data has changed or not. If the
data has changed, the sensor reboots
and starts from power-up.
3. Write your settings in the application
and then locate the NFC antenna of the
phone and sensor. Keep the two
devices close and do not move them to
get the best connectivity as possible
when writing or reading data to the
sensor. Bad connection can be caused
by long distance, wrong location, or
rapid movement.
4. When you have written data to the sensor, let the sensor reboot and restart
before trying to write again.
You should always validate your settings by reading the NFC data after the
sensor has restarted.

Sensor startup
1. When the sensor starts up, it loads
configuration from the internal memory and
merges it with user configuration.
2. When the configuration is done, the sensor
writes the new configuration to the NFC chip.
The sensor always writes new configurations
to the NFC chip when something changes in
the sensor or if NFC data is corrupted by an
NFC writer or phone. The sensor always writes
the new configuration to NFC chip at startup.
3. When the configuration is done, the sensor
tries to join the network if OTAA (Over the Air
Activation) is enabled.
4. The sensor LED flashes orange when it tries to
join a network. It will try to join every 10
seconds initially. This interval will increase to
save battery, at most up to one time per hour.
5. After successful connection to a network, the
sensor sends a settings packet and enters
sampling mode.
