Sensor Configurations

5 Sensor Behavior

ELT Series LoRa Operatingmanual

5.1 Sensor Startup
1. When the sensor starts up it loads any configuration parameters written to the NFC chip. The sensor will then write all configuration parameters back to the NFC chip.
2. When the configuration is done the sensor tries to join the network if OTAA (Over the Air Activation) is enabled. Make sure that the sensor credentials (DevEUI, AppKey, JoinEUI) match the keys added in the server for activation of the device. The join procedure starts at spreading factor 7 with a join request every ~15 seconds. The sensor will gradually increase the time as well as the Spreading Factor between the following join requests until the join is successful. Every join request is indicated by a yellow LED blink.
3. After successful connection to a network, the sensor sends an uplink containing the sensor settings and enters sampling mode.

5.2 Sampling mode / Periodic measurement
The sensor makes periodic measurements according to the user configuration.

5.3 Scheduled Transmission
The sensor transmits data according to the user configuration. However, the configured sending interval can be overridden by network limitations. Due to this, the spreading factor and sending interval settings might result in longer intervals than intended.

5.4 LED Indication
The LED, located in the bottom right corner on the PCB, indicates different actions when the sensor is active.

7 External Sensors

ELT Series LoRa Operatingmanual

The ELT series LoRa of sensors can be connected to a wide array of external sensors, equipment, and modules. All connections to external gear are made available through the terminal block located on the top left of the circuit board inside the ELT. Available connections on the terminal block are power, ground and either one or two multipurpose I/O-ports depending on the ELT variant.
7.1 General External Sensor Parameters
All of the following settings can be set using NFC and our app Sensor Settings or via a LoRaWAN downlink to the device.
External Sensor: Sets the external sensor type.
External Period: The external period sets how often the external sensor data is to be reported as a multiple of the sensors send period. Ensure that the external sensor send period is set to a non-zero value for the sensor to send external sensor data, including non-periodic data, as the default value is 0.
External Startup Time: The time in milliseconds between B+ power is applied to the external sensor is sampled. Set the External Startup Time to 1000000 or greater to make the B+ output always on. The function of this parameter may change depending on the external sensor parameter, consult the following sections for details.
External Trigger Timeout: The amount of time in milliseconds from a trigger event to when a new trigger is allowed. The External Trigger Timeout is used in the Pulse and Switch modes.

7.2 Power Output
The ELT sensors can power external sensors and modules using the B+ output on the terminal block. The output is controlled by the External Startup Time parameter. Set the External Startup Time to 1000000 or greater to make the B+ output always on.
In some modes, a default startup time is applied by the sensor. In these modes, only External Startup Time values greater than the default startup time are applied.
The B+ output voltage is not regulated, it is directly tied to the + pole of the battery.

ELT Series LoRa Operatingmanual

7.3 Analog Input
With the analog input modes set as external sensor type the sensor will wake up on main time base and measure the voltage at the input.
If the sensor has I/O2 the sensor will sample both inputs.
The reported value will be the voltage in mV. It can be set to measure two voltage ranges, 0-3 V or 0 10V, a mode where the ELT powers the source to be read is also available. Note that values for unconnected Analog inputs are undefined, meaning any number in the ADC may be reported for that channel. If a defined value is desired for unconnected inputs, connect a short jumper between the input and GND, which will result in the channel value being 0.
7.3.1 Analog Input 0-3 V Connect positive lead to IN and negative lead to GND on the terminal of the ELT. If the sensor has I/O2, a second source may be connected with the positive lead connected to I/O2 and negative lead to GND. The input impedance is approximately 50 k.

External sensors

7 External sensors

ELT Series LoRa Operatingmanual

7.3.2 Analog Input 0-10 V Connect positive lead to IN and negative lead to GND on the terminal of the ELT. The input impedance is approximately 6.5k on the IN terminal. If the sensor has I/O2, a second source may be connected with the positive lead connected to I/O2 and negative lead to GND. I/O2 is in 0-3 V range in this mode with an input impedance of approximately 50 k.

7.3.3 Powered Input 0-10 V Power to an external sensor can be applied on the B+ terminal if needed. This power is applied before sampling of the sensor with a time set with the parameter "External Startup Time".
Note: the B+ output voltage is not regulated, it is the battery positive voltage.

External Sensors

7 External sensors

ELT Series LoRa Operatingmanual

7.3.4 20 mA Input Select one of the Analog Input modes (See 7.3.1 and 7.3.2), connect a resistor (R) in parallel to the input, between IN and GND. Convert the voltage to current using Ohm's law, U=R*I. For full range use a 150 resistor in 3 V mode and a 536 resistor in 10 V mode.

7.4 Pulse Count
With any of the pulse counting modes set as external sensor type, the sensor will be continuously sampling the input. The external trigger timeout is used in all pulse modes (see 7.1 for details).
The voltage needs to be as close as possible to the internal sensor voltage to register as a pulse. The pulse input modes will work with both passive switches and active outputs.
There are two ways of counting. In normal counting the sensor will report the number of pulses registered since the last uplink. In absolute count mode, the sensor will keep the number of pulses so the reported value will be the number of pulses registered since the device was started. In absolute count mode the sensor will keep the pulse count. The pulse count will be kept if the sensor resets. The pulse count can only be reset/changed by sending a downlink command to the sensor.

7.4.1 Pulse Input Pull-up & Pulse Input Pull-up Absolute Count Connect positive lead to IN and negative lead to GND on the terminal of the ELT. If connected to an S0 output, connect the S0- lead to GND and S0+ lead to IN. The ELT will count all falling edges of the input signal. The ELT input is internally pulled up by approximately 50k .

7.4.2 Pulse Input Pull-down & Pulse Input Pull-down Absolute Count Connect positive lead to B+ and negative lead to IN on the terminal of the ELT. Set the ON-time parameter to 10 000 000 ms to make the B+ output always activated. The ELT will count all rising edges of the input signal. The ELT input is internally pulled down by approximately 50k .

7 External sensors

ELT Series LoRa Operatingmanual

7.4.3 Pulse Input no Pull-up/down & Pulse Input no pull-up/down Absolut Count Connect positive lead to IN and the negative lead to GND on the terminal of the ELT. The ELT will count all edges, positive and negative, of the input signal. The ELT input has no input pull up/down resistance in this mode. This requires the input signal to be driven both high and low by the external sensor. The voltage needs to be as close as possible to the internal sensor voltage in order to register as a pulse.

7.4.4 Pulse Input Pull-up, 2 channels Connect positive lead 1 to IN and positive lead 2 to I/O2, and negative lead(s) to GND on the terminal of the ELT. The pulse count of the channels will be reported separately. The ELT input is internally pulled up by approximately 50k .

7.4.5 Pulse Input Pull-down, 2 channels Connect positive lead 1 and 2 to B+, negative lead 1 to IN and negative lead lead 2 to I/O2. Set the ON-time parameter to 10 000 000 ms to make the B+ output always activated. The pulse count of the channels will be reported separately. The ELT input is internally pulled down by approximately 50k .

7.5 Switch Input
When set to a switch input mode, the sensor will apply digital logic to the input(s), with 0 used for the normal switch state and 1 for the active switch state. The switch state will be read by the sensor applying a voltage to IN and (when applicable) I/O2 using a 50k pull up resistor. The inputs are debounced using the standard external trigger timout, except for the Level Switch mode (see. 7.5.4)
7.5.1 Switch Input (Normally Open) Connect the switch leads to IN and GND. If the sensor has I/O2 two switches may be used in parallel, connect the second switch leads to I/O2 and GND. The sensor will send triggered messages when the switch closes as well as periodically, containing the current state of the switches. The reported values will be 1 for closed and 0 for open.

7.5.2 Switch Input (Normally Open), Dual Edge Trigger Connect the switch leads to IN and GND. If the sensor has I/O2 two switches may be used in parallel, connect the second switch leads to I/O2 and GND. The sensor will send triggered messages when the switch opens or closes as well as periodically, containing the current state of the switches. The reported values will be 1 for closed and 0 for open.

7.5.3 Switch Input (Normally Closed)
Note: Requires firmware version 2.4.6 or later. When set to switch NC the sensor will wake up every 10 seconds and apply voltage to the IN and (if applicable) I/O2 ports with pull-up resistors to test if the circuit is closed. An uplink will be sent if the switch opens or closes as well as periodically, containing the current state of the switches. If the sensor has I/O2 two switches may be used in parallel, connect the second switch leads to I/O2 and GND. The reported values will be 0 for closed and 1 for open.

7 External sensors

ELT Series LoRa Operatingmanual

7.5.5 Switch Input, Door
Note: Requires firmware version 2.4.6 or later. Connect the switch leads to IN and GND, if applicable connect a second switch to I/O2 and GND. When set to Switch Input Door, the sensor will send a triggered message containing the current state of the switch when the switch is opened or closed, then wait for a user-selectable amount time, then send a message containing the number of openings/closings that has occurred during the wait. In this mode, the "External Startup Time" parameter sets the wait time in milliseconds. Debounce may be used and is set using the "External Trigger Timeout" parameter. The reported values will be 1 for closed and 0 for open.

7.6 Digital Input
Connect the positive leads to IN and I/O2 and the negative lead to GND. The sensor will read external voltage provided by the external source and report `0' or `1'. The input will be periodically sampled and reported.

7.7 Temperature Probe DS18B20
The ELT is compatible with DS18B20 1-wire temperature probes. When connected to the ELT the probes will be set to 12-bit-mode. Six DS18B20 can be connected to the same ELT at once (ELT lite supports one DS18B20). The first probe temperature will be reported as "External Temperature 1" and all other probes will be reported as "External Temperature 2". Connect the black lead(s) to GND, the yellow lead(s) to IN and red lead(s) to B+

7.8 Water leak
The water leak mode measures conductivity between two wires which can be used to detect water and moisture. The reported values are 0-255 where higher values means higher conductivity. Note that longer water leak cables have a higher base conductivity, this needs to be measured after the cables have been installed and an appropriate alarm level will need to be set in the backend system. Connect the unshielded wires to IN and I/O2, make sure they aren't touching each other as that will result in the sensor always measuring maximum conductance.

Picture is for illustrative purposes only. The water sense leads does not need to extend the black and yellow wires.
