1. Introduction

RA08B series is a Class A device based on LoRaWAN open protocol. It could be used for temperature, CO2, PIR, air pressure,

illuminance, TVOC, and NH3/H2S detection. Data collected by sensors would be shown on the E-ink display. Users are able to know the

data through one quick peek.

LoRa Wireless Technology:

LoRa is a wireless communication technology that adopts techniques such as long-distance communication and low power

consumption. Compared with other communication methods, LoRa spread-spectrum modulation techniques greatly expand the

communication distance. It is used in long-distance and low-data wireless communications like automatic meter reading, building

automation equipment, wireless security systems, and industrial monitoring control system. The features include small size, low

power consumption, long transmission distance, and anti-interference ability.

LoRaWAN:

LoRaWAN built LoRa’s end-to-end standards and techniques, ensuring interoperability between devices and gateways from different

manufacturers.

4. Set-up Instruction

4.1 On/Off

Power on

Insert batteries. (Users may need a screwdriver to open battery cover.)

Turn on

Press and hold the function key for 3 seconds until the green indicator flashes.

Turn off

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

Remove Batteries.

Note

1. When user removes and inserts the battery; 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

Please 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

Long press the function key for 5 seconds and the green indicator flashes once.

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

Long press the function key for 5 seconds the green indicator flash once.

Keep pressing the function key for more than 10 seconds, the green indicator flashes 20 times.

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

Note

User should wait at least 3 seconds to press the function key again or it would not work properly.

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

1. Please remove the batteries when the device is not in use.

2. Please check the device verification information on the gateway.

4.5 Low Voltage Warning

Low Voltage

3.2 V

5. Data Report

After power 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 when no configuration is done.

Please do not send commands without turning on the device.

Default Setting:

Max Interval: 0x0708 (1800s)

Min Interval: 0x0708 (1800s) // The Max and Min Interval shall not be less than 180s.

IRDisableTime: 0x001E (30s)

IRDectionTime: 0x012C (300s)

CO2:

(1) Fluctuation of CO2 data caused by delivery and storage time could be calibrated.

(2) Please refer to 5.2 Example of ConfigureCmd and 7. CO2Sensor Calibration for detailed information.

TVOC:

(1) Two hours after power on, the data sent by TVOC sensor are for reference only.

(2) If the data is way higher or below the setting, the device should be placed in the environment with fresh air in 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

Data 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, disconnection, and errors of sensors.

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.

//ACK = 0x00 (OFF), interval of data packets = 10s;

//ACK = 0x01 (ON), interval of data packets = 30s (cannot be configured)

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:

Tips

1. Battery Voltage:

The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.

Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage.

The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v

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.
