4Product Description
The OY1211 LoRaWAN CO2 meter is designed to measure carbon dioxide, temperature and
humidity in indoor environments. The sensor is intended for indoor climate control, air
quality monitoring and energy optimizations. It is optimized for reliable and secure
measurements with more than 5-10 years life length on batteries dependent on radio
conditions.
The standard measurement interval is every minute and standard reporting interval is every 25
measurements (resulting in a measurement report transmitted every 25 minutes). The fast
measurement interval makes it possible to insert additional transmissions when large changes
in the CO2 level are detected, resulting in low reporting latency. By default, CO2 level
changes larger than +/-100ppm from the last transmitted measurement report causes an
additional measurement report over the LoRa uplink channel. If the absolute CO2 level is
below a certain threshold, by default 750ppm, these additional reporting events are however
omitted. All these parameters can be adjusted using LoRa downlink commands if needed.

What value does this provide, climate control, active ventilation etc.
5Advanced settings
The device has advanced settings that such as configuration of automatic background
calibration (ABC) functionality, target calibration, and sub-sample settings. The settings are
impacting the power and accuracy performance of the device. Contact
[email protected] for detailed information.

6Installation and activation
The sensor consists of a bottom piece, the electronic board and the top cover. Remove the top
cover by pressing it upwards and outwards. The electronics are removed by releasing the
plastic latch on the top.
The bottom piece is mounted on the wall with the “UP” arrow upwards. It can be mounted
either with screws or adhesive tape.

Configure the device in the LoRaWAN server, according to chapter 5.1, and insert the
batteries. The sensor starts and flashes 2 + 6 times during the boot-up sequence. The sensor is
activated by pressing the push button for 3 seconds until the red LED makes two short
flashes. When the device has successfully joined the LoRaWAN network there will be a 2-
second-long flash. Attach the electronic board to the bottom piece and attach the plastic cover.
6.1 LoRaWAN Configuration
Configuration on the network server is done with
AppEUI: 70-B3-D5-D7-2F-F8-18-00 (a.k.a. JoinEUI)
It is possible to order a batch of devices configured with a customer unique AppEUI from the
Talkpool OUI range.
The device is configured with device unique DevEUI and AppKey. The DevEUI is printed on
device box and the AppKey is distributed by the sales team. The device is default configured
for OTA provisioning. Contact the Talkpool team for ABP configuration. The device follows
the LoRaWAN standard related Join configuration parameters, such as RX1 and RX2
windows, RX2 downlink frequency etc.
The default setting is ADR enabled.
If you are not experienced of LoRaWAN, contact [email protected] to get started.

6.2 Sensor states and state check
The sensor has five states: Booting, Initial, Joining, Configure and Operational state.
Figure 1 Device states
When the unit is initially powered, it flashes 2 times with the LED, after a few seconds the
unit enters initial state automatically. This is indicated by flashing 6 times.
To check the device state, press the button and hold it pressed until the red LED starts
flashing after 0.5s.
State
Description
LED response
Initial
Low power state during transport. Radio not active.
1 short flash (0.5 sec)
Joining
Trying to join a LoRaWAN network. The device
will remain in this state until successfully joined a
LoRaWAN network
2 short flash (0.5 sec)
Configure
Enables quick over-the-air configuration, by polling
server after configuration commands during 2
minutes. This is done by sending uplink status
command (0x20).
1 long flash (2 sec)
Operational
Joined to a LoRaWAN network, measures
temperature and humidity periodically, and sends
measurement reports toward a LoRAWAN network.
1 long flash (2 sec)

6.2.1 Re-join functionality
The device supervises its connectivity to the network, by monitoring that periodic downlink
messages are received.
The device tries to re-join the network if it has not heard anything from the network for 288
uplinks (4 days @ 20-minute message interval). The device requests and normally gets a
downlink ever 64th uplink due to the ADRAckReq functionality.
