1. Introduction
RA08D series is a Class A device based on LoRaWan open protocol. It could be used for temperature/humidity, CO2, PIR, air
pressure, illuminance, TVOC, PM2.5, CH2O, O3, and CO detection. Data collected by sensors would be shown on the E-ink display.
Users are able to know the data through one quick peek.
Note: For more information of RA08D series and its sensors, please refer to 7. RA08D and Sensor Configuration.
2. Appearance
RA08D08
3. Features
⚫SX1276 wireless communication module
⚫Powered by DC 12V adapter
⚫IP65 rating*
⚫Compatible with LoRaWANTM Class A device
⚫Frequency hopping spread spectrum
⚫Reading data and setting alarms on SMS or email by configuring parameters through third-party platforms (optional)
⚫Support third-party platforms: Actility/ThingPark, TTN, MyDevices/Cayenne
Note: The waterproof membrane stops liquid water from passing into the device. However, it does not contain a water vapor barrier. To
prevent water vapor from condensing, the device should not be used in an environment that is highly humid or full of vapor.

4. Setup Instruction
4.1 On/Off
Power on
Connect to power supply
Turn on
The green indicator flashes once.
Reboot
Press and hold the function key for 5 seconds until green indicator flashes once.
Then release the function key. The device will automatically shut down after the indicator flashes
10 times.
Reset to factory setting
Press and hold the function key for 10 seconds until green indicator flashes fast for 20 times.
The device will reset to factory setting and automatically shut down.
Power off
Disconnect the power supply
Note
1.When user disconnects the power supply; the device should be off by default.
2. 5 seconds after power on, the device will be in engineering test mode
3. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor
inductance and other energy storage components.
4.2 Network Joining
Never joined the network
Turn on the device to search the network to join.
The green indicator stays on for 5 seconds: Success
The green indicator remains off: Fail
Had joined the network
(without factory resetting)
Turn on the device to search the previous network to join.
The green indicator stays on for 5 seconds: Success
The green indicator remains off: Fail
Fail to join the network
Note:
1. To save energy, the power supply should be disconnected when the device is not in use.
2. User is recommended to check the device verification information on the gateway or consult
your platform server provider.
4.3 Function Key
Press and hold for 5 seconds
Turn off and Restart
Long press the function key for 5 seconds and the green indicator flashes 10 times.
Release the function key and the green indicator flashes 10 times.
The green indicator remains off: Fail
Press and hold for 10 seconds
Reset to factory setting / Turn off
The green indicator flashes 20 times: Success
The green indicator remains off: Fail

4
Short press
The device is in the network: green indicator flashes once, screen refreshes once, and send a data
report
The device is not in the network: screen refreshes once and the green indicator remains off
4.4 Sleeping Mode
The device is on and
in the network
Sleeping period: Min Interval.
When the reportchange exceeds the setting value or the state changes, the device will send a data
report based on the Min Interval.
The device is on but
not in the network
Note:
1. Users should disconnect the power supply when the device is not in use.
2. Users are recommended to check the device verification information on the gateway

5
5. Data Report
After powering on, the device would refresh the information on the screen and send a version packet report along with an uplink
packet.
Note: 1. The interval of data packets would be 10 seconds by default. When the ack = 0x01, the intervals would be 30 seconds.
2. Two hours after powering on, the data sent by devices with TVOC sensors are for reference only. If the data is way higher
or below the setting, the device should be placed in an environment with fresh air for 24 to 48 hours until the data is back
to normal value.
3. The device sends data based on the default configuration before any configuration is done. Please do not send commands
without turning on the device.
Default Setting: Max Interval: 0x384 (900s)
Min Interval: 0x384 (900s)
Note: The Max and Min Intervals shall not be less than 5 minutes for devices with CH2O and O3 sensors.
The Max and Min Intervals shall not be less than 3 minutes for the rest of the devices.
Data collecting and transmission:
Join the network: press the function key (indicator flashes once) / trigger PIR, read data, refresh screen, report detected data (based
on the report interval)
Without joining the network: press the function key / trigger PIR to get data and refresh the information on the screen.
The information shown on the E-ink display:
1. FFFF of reported data and “—” on the screen means the sensors are turning on or disconnection and errors of sensors.
2. The information shown on the screen is based on user’s choice of sensor. It would be refreshed by pressing the function key,
triggering the PIR, or refreshed based on the report interval.

Note: 1. Fluctuation of CO2 data caused by delivery and storage time could be calibrated. Please refer to 5.2 Example of
ConfigureCmd for detailed information.
2. TVOC level
Very good
< 150 ppm
Good
150-500 ppm
Medium
500-1500 ppm
Poor
1500-5000 ppm
Bad
> 5000 ppm
3. Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver
http://www.netvox.com.cn:8888/cmddoc to resolve uplink data.
Data report configuration and sending period are as follows:

Tips
1. Battery Voltage:
If the battery is equal to 0x00, it means that the device is powered by a DC power supply.
2. Version Packet:
When Report Type=0x00 is the version packet, such as 01A0000A01202307030000, the firmware version is 2023.07.03.
3. Data Packet:
When Report Type=0x01 is data packet.
(If the device data exceeds 11 bytes or there are shared data packets, the Report Type will have different values.)
4. Signed Value:
When the temperature is negative, 2's complement should be calculated.

• Do not put the device near or submerge into water. Minerals in rain, moisture, and other liquids could cause corrosion of electronic
components. Please dry the device, if it gets wet.
• Do not use or store the device in dusty or dirty environments to prevent damage to parts and electronic components.
• Do not store the device in high temperatures. This may shorten the lifespan of electronic components, damage batteries, and deform
plastic parts.
• Do not store the device in cold temperatures. Moisture may damage circuit boards as the temperatures rise.
• Do not throw or cause other unnecessary shocks to the device. This may damage internal circuits and delicate components.
• Do not clean the device with strong chemicals, detergents, or strong detergents.
• Do not apply the device with paint. This may block detachable parts and cause malfunction.
• Do not dispose of batteries in fire to prevent explosion.
The instructions are applied to your device, battery, and accessories. If any device is not working properly or has been damaged, please
send it to the nearest authorized service provider for service.
