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

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. 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:

Min. Interval

(Unit: second)

Max. Interval

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.
