The ERS Display series of sensors are universal LoRaWAN® indoor climate sensors with a 2.1” E-paper display
showing real-time sensor data. Depending on the model, the sensor measures temperature, humidity, light intensity,
CO2 level, VOC level, and sound level and detects motion. The ERS Display series are battery-powered devices
and are designed to be wall-mounted. The sensors are equipped with NFC (Near Field Communication) for easy
configuration with an NFC-enabled smartphone.

ERS Display Series Operating manual
2 Mounting Guidelines
Common mounting guidelines for ERS Display Series line of sensors:
• Place the sensor in an open space on the wall, with an installation height of 1.6 meters.
• For best RF and measurement performance, make sure you mount the sensor with the ventilation openings
vertically. See installation in chapter 3.
• Make sure that the sensor is not placed in direct sunlight, close to heating vents, near windows, air ventilation
where it may measure values that is not representative for the rest of the room.
2.1 Motion PIR
The PIR can self-trigger if sensors are placed too close to each other. Keep this in mind when you mount or test
the sensors.
2.2 Sound Level
Think carefully about the placement of the sound sensor. If the sensor is placed close to loud sources such as
machines or ventilation, it will be reflected in the sensor readings due to sounds being louder close to the source.
7Mounting Guidelines

1. Remove the back panel of the sensor by gently prying the tab with a small screwdriver. Take care
not to damage any internal components.
2. Install the batteries. The ERS2 requires one or two AA batteries. The battery type is 3.6V Lithium Battery
(ER14505). You can use one battery, but it’s recommended that you use two for best performance and
battery life. Use battery slot A if only one battery is used.
3 Installation
3. Mount the back panel securely to the wall with at least 2 appropriate screws, using some of the four
mounting holes. Alternatively, attach the sensor with double sided adhesive tape.

4 Sensor Configuration
10 Sensor 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.
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.

4.3 Application Parameters
NFC
Antenna
Operating manual
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
endusers unable to read or change settings on the sensor.
1. Download ELSYS “Sensor Settings” application from Google Play or App Store and install it on a smart
phone 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 EMS sensor to connect with the NFC antenna. Keep the two devices
close to each other and don’t move them to get as good connectivity as possible. You may need to
remove the top cover and battery to get connection.
4. Current settings will be displayed in the application.
5. Use the application to change any settings if needed.
6. Tap the device on top of the NFC antenna to send the new settings to the sensor. Make sure that the
application confirms your new settings.
7. Wait for the sensor to reboot (1-5 sec), indicated by the LED flashing. Sensor settings have been
updated. Always validate your settings by reading the NFC data after the sensor has restarted.
See the section “Help” in the application for more information.

5 Display
11Display
The ERS Display series sensors have a 2.13” E-paper display, which keeps the onscreen information even if the
sensor is unpowered.
The display will have four different modes depending on the current state of the sensor.
Factory mode: If the sensor is not yet started. See figure 1.
Join mode: When the sensor is trying to join the network. See figure 2.
Standard mode: During normal operation, the layout and values presented on the screen will depend on the
sensor model and configuration. See figure 3, 4 and 5.
Low Battery mode: If the sensor detects that the battery voltage is getting close to the limit of operation, the
sensor will set the screen to display information that the battery needs to be replaced. It will not recover from this
mode until the batteries are replaced. See figure 6.
Operating manual
5.1 Display

The sensor will perform a full refresh of the screen every 72nd time it updates. During a full refresh, the display
will flash back and forth between completely black and completely white before the new content is shown.

The display is updated on a multiple of the main time base, which will be 1 by default. The onscreen values are
the most recently measured as decided by the internal sensors' sample periods. The temperature unit can be
configured to be shown as either Celsius or Fahrenheit. On-screen text information in standard mode can be
selected by the user. Available languages are English, German, French, Italian and Spanish.

6 Sensor Behavior
13Sensor Behavior
1. The display will be set to factory mode before the sensor is powered for the first time.
2. When the sensor starts, it loads configuration parameters stored in the NFC chip. The sensor will then write
all configuration parameters back to the NFC chip.
3. When the configuration is done, the sensor tries to join the network if OTAA (Over the Air Activation) is en-
abled. Ensure that the sensor credentials (DevEUI, AppKey, JoinEUI) match the keys added to the server to
activate the device. The join procedure starts at spreading factor 7 with a join request every ~15 seconds.
The sensor will gradually increase the time and the Spreading Factor between the following join requests until
the join is successful. An orange LED blink indicates every join request.
The sensor starting the join procedure will be indicated on display with the join mode screen.
4. After a successful connection to a network, the sensor sends an uplink containing the sensor settings and
enters sampling mode. The screen enters its default mode of showing sensor data.
Operating manual
6.1 Sensor Startup
The sensor makes periodic measurements according to the user configuration
6.2 Sampling mode / Periodic measurement
The sensor transmits the 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.

The light sensor sits behind the PIR lens. For correct reading, make sure it isn’t obstructed. Accuracy can depend
on angle of light source.
The CO2sensor normally runs an automatic baseline correction algorithm (ABC), with a period of 8 days. For
a fully corrected measurement, the ABC needs 3 consecutive 8-day periods where the sensor sees fresh air
sometime during each ABC period. It can also be calibrated manually, and the ABC can be turned off. In this
case it is recommended to do a manual calibration in fresh air once/year.
Measurement range, Ethanol or Hydrogen in air: 0-1000000ppb*
*Conversion from ppm to mg/m3 for most common TVOC is by the factor approximately 2 (e.g., 1ppm equals
approximately 2mg/m 3).

7.6 Motion PIR Sensor
Actual range of the sensor can be influenced by environmental conditions. Avoid installing the sensor in areas
where it will face direct or reflected sunlight. Avoid installing near windows, air conditioning, or heating vents.
Such placements can give false values.
The PIR can cause self-trigger if sensors are placed too close to each other. Keep this in mind when you mount
or test the sensors.
The PIR has a blanking time of 8 seconds right after motion event and transmission. Any movements during this
time will be ignored.

The sound level sensor continuously measures the average and peak sound pressure level with no missing

average value. The digital part wakes and samples both signals every 10 s and does the final calculation before
sending the data at the desired send interval.
