1. Description
The ERS is a universal indoor climate sensor for LoRaWANTM wireless network.
The sensor measures temperature, humidity, light intensity*, CO2*, sound
level and detects moon*. The ERS is a baery powered device and designed
to be installed quickly and easily. The moon sensor can be used for presence
monitoring systems. All ERS sensors are equipped with NFC (Near Field
Communicaon). Once it is powered, you can use the Sensor Sengs applicaon
to control your sensor using your Android phone.

downlink data to the sensor. Sampling rate, spreading factor, encrypon keys,
port and modes can be changed. All sensor sengs can be locked from the server
or NFC and end users cannot read or change sengs on the sensor.
3.1 Android application on smartphone or tablet
1.Download Elsys “Sensor Sengs” applicaon from Google Play Store and install
it on an Android smartphone or tablet. The device must support NFC.
2. Enable NFC on the device and start the applicaon.

4. Sensor application Sensor startup
When the sensor starts up it loads conguraon from the internal memory and
merge it with user conguraon. When the conguraon is done the sensor
writes the new conguraon to the NFC chip. The sensor always writes new
conguraons to the NFC chip when something changes in the sensor or if
NFC data is corrupted by a NFC writer or phone. The sensor always writes new
conguraon to NFC chip at startup. When conguraon is done the sensor tries
to join the network if OTAA (Over The Air Acvaon) is enabled. The sensor led
ashes orange when it tries to join a network. The sensor tries to join the network
every 10 second and increases the join mer at every failed aempt by
10%, up to maximum 1 hour. Aer startup, conguraon and join the sensor
enters sampling mode.
4.1 NFC read/write
When reading or wring NFC conguraon data to the sensor it starts a mer and
delays its acon x seconds. It delays its acon because of the bad connecon that
can be in NFC communicaon. Types of bad connecon can be distance, locaon
or rapid movement. Aer the delay the sensor determines if the NFC data has
changed or not. If the data has change the sensor reboots and starts from power
up. When wring data to the sensor try to get the best connecvity as possibly.
Locate the NFC antenna of the phone and sensor. Keep the 2 devices as close as
possible and don’t move them while wring or reading. When you have wrien
data to the sensor, let the sensor reboot and restart before trying to write again.
You can always validate your sengs by reading the NFC data aer the sensor has
restarted.

Sensor application
Sensor startup
When the sensor starts up it loads configuration from the
internal memory and merge it with user configuration. When
the configuration is done the sensor writes the new
configuration to the NFC chip. The sensor always writes new
configurations to the NFC
chip when something
changes in the sensor or if
NFC data is corrupted by a
NFC writer or phone. The
sensor always writes new
configuration to NFC chip at
startup. When configuration
is done the sensor tries to
join the network if OTAA
(Over The Air Activation) is
enabled.The sensor led
flashes orange when it tries
to join a network. The sensor
tries to join the network
every 10 second and
increases the join timer at
every failed attempt by
10%, up to maximum 1 hour.
After startup, configuration
and join the sensor enters
sampling mode.

NFC read/write
When reading or writing NFC configuration data to the sensor
it starts a timer and delays its action x seconds. It delays its
action because of the bad connection that can be in NFC
communication. Types of bad connection can be distance,
location or rapid movement. After the delay the sensor
determines if the NFC data has changed or not. If the data
has change the sensor reboots and starts from power up.
When writing data to the sensor try to get the best
connectivity as possibly. Locate the NFC antenna of the
phone and sensor. Keep the 2 devices as close as possible
and don’t move them while writing or reading. When you have
written data to the sensor, let the sensor reboot and restart
before trying to write again. You can always validate your
settings by reading the NFC data after the sensor has
restarted.
