Description
ELT-2 is a universal outdoor device for LoRaWAN® wireless network. It is
designed to be in extreme conditions and can measure analog or digital signals.
Use it together with electricity meters, flow meters, analog sensors, moisture
sensors and other external sensors. ELT-2 is enclosed in an IP67 box and have
four internal sensors: temperature sensor, humidity sensor, accelerometer and an
atmospheric pressure sensor. 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
of your device,

Installation
1. Remove the front lid of the sensor by removing the four screws.
2. Install the battery. The ELT-2 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. Connect any eventual external sensors.
4. Close the lid and tighten the screws carefully. Make sure that the cable
gland and antenna connection is tightened to prevent ingress of
moisture.

Powered analog input 0 –10V
Input signal between input and ground. +3V present at B+ pin.
Select “Analog input” in the application “Sensor Settings”. Select “Eternal startup time”
and configure ON-time for sensor. External startup time is how long the sensor will be
powered before sampling value. ELT input is internally pulled down and the input
impedance is 7.4 kΩ
Switch Input (Pull up)
Input signal between input and ground.
Select “Switch (Normally open)” in the application “Sensor Settings”. ELT input is
internally pulled up by ~50 k Ω*.
