Water leak input ELT 2

ELT 2 is a general LoRaWAN™ device for measuring analog or digital signals. ELT 2 can, for example, be used together with electricity meters, flow meters, analog sensors, moisture sensors, temperature sensors, water leak cable. It is enclosed in an IP65 box and is designed to be outside. Inside the ELT 2 you will find four internal sensors: a temperature sensor, a humidity sensor, an accelerometer for orientation measurements. and an atmospheric pressure sensor. A 3,6V AA lithium battery powers it. The Battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate, power output, and environmental factors. You are welcome to use our online battery lifetime calculator.
All Elsys’s sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. With our application “Sensor Settings”, you can change the sample rate, data rate, encryption keys, triggers, activation and much more. All of our software is built on top of the LoRaWAN™ stack from Semtech.
Channel plans exist for US902-928, EU863-870, AS923, AU915-928, KR920-923. ELT Lite is the lite version of ELT2.

Temperature sensor input

Temperature sensor input. ELT-1 is configured for 1-wire interface. Connect a DS18B20 compatible sensor. Select “Temperature sensor 1 wire” in android application “Sensor Settings”. ELT input is internally pulled up by 2.2kΩ.

Analog input 0-3 Voltage

Analog input (0-3V), input signal between input and ground.
Select “Analog input 0-3V” in android application “Sensor Settings”.
ELT input is internally pulled down.

Analog input 0-10 Voltage

Analog input (0-10V), input signal between input and ground.
Select “Analog input” in android application “Sensor Settings”.
ELT input is internally pulled down, and the input impedance is 7.4 kΩ.

Powered analog input

Analog input (0-10V), input signal between input and ground. +3V present at B+ pin.
Select “Analog input” in android application “Sensor Settings”. Select “Eternal startup time” in “Sensor Settings” 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

Pulse count (pull up)

Pulse count input, input signal between input and ground
Select “Pulse input(pull up)” in android application “Sensor Settings”. ELT input is internally pulled up by ~50 kΩ*.

Pulse count (pull down)

Pulse count input, input signal between input and B+. Select “External startup time” in “Sensor Settings” and configure ON-time for always on that is >1000000ms.
Select “Pulse input(pull down)” in android application “Sensor Settings”. ELT input is internally pulled down by ~50 kΩ*.

Pulse count (pull down) – External pulse

Pulse count input, input signal between input and GND. Pulse signal  from 3 to 12 voltage.
Select “Pulse input(pull down)” in android application “Sensor Settings”. ELT input is internally pulled down by ~50 kΩ*.

Pulse count (pull up) -S0 input

Pulse count input, S0 signal between input and ground
Select “Pulse input(pull up)” in android application “Sensor Settings”. ELT input is internally pulled up by ~50 kΩ*.

4-20mA input

4-20mA sensor input. Select “Analog input” in android application “Sensor Settings”. Connect resistor parallel to the input. Value of R can be calculated as R=UxI. For full range, use 500Ω resistor. (20mA will then read as 10V)
