4 Product Description
The OY1700 LoRaWAN Air quality (PM) sensor is designed to measure PM10, PM2.5,
PM1.0, temperature and humidity in indoor environments. The sensor is intended for indoor
climate control and monitoring indoor air quality. It is optimized for reliable and secure
operations.
The standard measurement and reporting interval are every 20 minutes, other reporting
intervals can be configured over the air.

5 Installation 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 both included in the package. The hole pattern matches
standard junction box.

Configure the device in the LoRaWAN server, according to chapter 5.1, and power the device
with 5-24 VDC power, e.g. USB charger or 24 VDC. The cable can be routed through the
cable canal or through the electronic board for junction box mount. The sensor starts and
flashes 8 times during the boot-up sequence and starts the join sequence to the LoRaWAN
network
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.

5.1 LoRaWAN Configuration
Configuration on the network server is done with
AppEUI: 70-B3-D5-D7-2F-F8-17-00 (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.
5.2 Sensor states and state check
The sensor has four states: Initial, Joining, Configure and Operational state.

Figure 1 Device states
When the unit is initially powered, it flashes 8 time with the LED, and tries to join the
LoRaWAN network. A successful join is indicated with a 2 sec long flash.
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 after initial boot. 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 for 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)
5.2.1 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 (3 days @ 15-minute message interval). The device requests and normally gets a
downlink ever 64th uplink due to the ADRAckReq functionality.
