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 6. RA08D and Sensor Configuration.

3. Features

SX1262 wireless communication module.

Powered by DC 12V adapter.

Compatible with LoRaWANTM Class A device.

Frequency hopping spread spectrum.

Support third-party platforms: Actility/ThingPark, TTN, MyDevices/Cayenne.

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. 5 seconds after power on, the device will be in engineering test mode

. 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 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.

The device sends data based on the default configuration before any configuration is done. Please do not send commands without

turning on the device.

CO2:

Fluctuation of CO2data caused by delivery and storage time could be calibrated.

Please refer to 5.2 Example of ConfigureCmd for detailed information.

TVOC:

(1)Two hours after powering on, the data sent by devices with TVOC sensors are for reference only.

(2) 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) TVOC level:

Very good

< 150 ppm

Good

150-500 ppm

Medium

500-1500 ppm

Poor

1500-5000 ppm

Bad

> 5000 ppm

The information shown on the E-ink display:

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.

// FFFF of reported data and “—” on the screen means the sensors are turning on or disconnection and errors of sensors.

Default Setting:

Max Interval: 0x0384 (900s)

Min Interval: 0x0384 (900s)

// 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.

IRDisableTime: 0x001E (30s)

IRDectionTime: 0x012C (300s)

Data collecting and transmission:

(1)Join the network:

Press the function key (indicator flashes once) / trigger PIR, read data, refresh screen, report detected data (based on the report

interval)

(2)Without joining the network:

Press the function key / trigger PIR to get data and refresh the information on the screen.

// The interval of data packets would be 10 seconds by default.

// When the ack = 0x01, the intervals would be 30 seconds.

Note:

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

(Unit: second) Detection Interval Report Interval

180 to 65535 180 to 65535 MinTime Exceed the setting value: report based on the

MinTime or the MaxTime 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.
