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

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.

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.

Installation

Installation

Remove the back panel of the sensor by gently prying the tab with a small screwdriver. Take care not to damage any internal components.
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.
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.
Attach the sensor part by hinging it on the back panel.

Service and Maintenance

There are no serviceable parts inside. If service is needed other than battery replacement, please get in touch with your distributor.

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 endusers unable to read or change settings on the sensor.

NFC Configuration

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.
Enable NFC on the device and start the application.
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.
Current settings will be displayed in the application.
Use the application to change any settings if needed.
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.
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 restarte

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.

Display

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.

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.

Onscreen sensor data

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.

Sensor Behavior

Sensor Startup

The display will be set to factory mode before the sensor is powered for the first time.
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.
When the configuration is done, the sensor tries to join the network if OTAA (Over the Air Activation) is enabled. 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.
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.

Sampling mode / Periodic measurement

The sensor makes periodic measurements according to the user configuration

Scheduled Transmission

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.

LED Indication

Temperature Sensor

Resolution	0.1 °C
Accuracy	0.2 °C typical, see figure 7

Humidity Sensor

Resolution	1 % RH
Accuracy at 25 °C	±2 % RH, see figure 8

For accuracy of RH over temperature, see figure 9

Light Sensor

Range	0 – 65535 lux
Accuracy	± 10 % or ± 10 lux, whichever is greater.

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.

CO2 Sensor

Range	400 – 5000 ppm
Accuracy	30 ppm, ±3 % of reading (15-35 °C, 0-80 % RH)

The CO2
sensor 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.

VOC Sensor

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).

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.

PIR Lens Detection Pattern

Lens for Temperature & HumidityPro and Air QualityPro.

PIR Lens Detection Pattern

Sound Level Sensor

Average Value Range	32 – 75 dBspl
Peak Value Range	60 – 99 dBspl
Filtering	dBal
Sound Resolution	1 dB
Sound Accuracy	±5 dB

The sound level sensor continuously measures the average and peak sound pressure level with no missing events. The analog part is always on, with a peak-hold circuit for peak level, and a mean-value filtering for 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.

Sound Level Sensor

10 s sample and peak reset. For every send interval, it calculates total peak and average for all samples. Red = peak, yellow = average.
