1. Introduction

1.1 What is AIS01-CB

AIS01-CB is a NB-IoT/LTE-M AI Image End Node. AIS01-CB has a camera and AI processor in the probe. It can take photo , analyze the photo to get digital reading and upload to IoT server via NB-IoT/CAT-M1 network.

AIS01-CB is pre-trained to support image recognized of water meter, gas meter and power meter. It can be trained to support more image recognized for different application.

AIS01-CB can send the digital reading after recognized and it can also send the original photo via NB-IoT/CAT-M1 as well.

AIS01-CB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.

AIS01-CB supports BLE configure and OTA update which make user easy to use.

AIS01-CB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

Behavior on ACTFunctionAction
Pressing ACT between 1s < time < 3sSend an uplink

If sensor is already Joined to LoRaWAN network, sensor will send an uplink packet, blue led will blink once.
Meanwhile, BLE module will be active and user can connect via BLE to configure device.

Pressing ACT for more than 3sActive Device

Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to JOIN LoRaWAN network.
Green led will solidly turn on for 5 seconds after joined in network.
Once sensor is active, BLE module will be active and user can connect via BLE to configure device, no matter if device join or not join LoRaWAN network.

Fast press ACT 5 times.Deactivate DeviceRed led will solid on for 5 seconds. Means device is in Deep Sleep Mode.

1.6 BLE connection

AIS01-CB supports BLE remote configure.

BLE can be used to configure the parameter of sensor or see the console output from sensor. BLE will be only activate on below case:

  • Press button to send an uplink
  • Press button to active device.
  • Device Power on or reset.

If there is no activity connection on BLE in 60 seconds, sensor will shut down BLE module to enter low power mode.

2. Use AIS01-CB to communicate with IoT Server

2.1 Send data to IoT server via NB-IoT/CAT-M1 network

The AIS01-CB is equipped with a NB-IoT module, the pre-loaded firmware in AIS01-CB will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by AIS01-CB.

Below shows the network structure:

image-20240814164431-1.png

There are two version: -GE and -1T version of AIS01-CB.

GE Version: This version doesn't include SIM card or point to any IoT server. User needs to use AT Commands to configure below two steps to set AIS01-CB send data to IoT server.

  • Install NB-IoT SIM card and configure APN. See instruction of Attach Network.

Below shows result of different server as a glance.

image-20240816102546-2.png

image-20240816101222-1.png

Version:

These bytes include the hardware and software version.

Higher byte: Specify Sensor Model: 0x68 for AIS01-CB

Lower byte: Specify the software version: 0x64=100, means firmware version 1.0.0

BAT (Battery Info):

Ex1: 0x0da6 = 3494mV

Signal Strength:

NB-IoT Network signal Strength.

Ex1: 0x1f = 31

0        -113dBm or less

1        -111dBm

2...30 -109dBm... -53dBm

31      -51dBm or greater

99      Not known or not detectable

Interrupt:

This data field shows if this packet is generated by interrupt or not.

Example:

If byte[0]&0x01=0x00 : Normal uplink packet.

If byte[0]&0x01=0x01 : Interrupt Uplink Packet.

Interrupt_level:

This byte shows whether the interrupt is triggered by a high or low level.

Ex1: 0x00  Interrupt triggered by falling edge (low level)

Ex2: 0x01  Interrupt triggered by rising edge (high level)

Reading: 

The uplink integer data is the first four bytes of the Reading payload.

Ex1: 0x00000655(H) = 1621(D)

The fractional part is the last four bytes of the uplink Reading payload.

Ex2: 0x00000094(H) = 148(D) / 1000000 = 0.000148

The total number read is:

integer part(D) + decimal part(D): 1621+0.000148=1621.000148

TimeStamp & GPS Timestamp

Unit TimeStamp Example: 66beb5c3(H) = 1723774403(D)

Put the decimal value into this link(https://www.epochconverter.com/) to get the time.

3. (Trigger by rising edge)

OK
AT+INTMOD2=2Set Transmit Interval
0. (Disable Interrupt),
1. (Trigger by rising and falling edge)
2. (Trigger by falling edge)
3. (Trigger by rising edge)
OK

Downlink Command: 0x06

Format: Command Code (0x06) followed by 3 bytes.

This means that the interrupt mode of the end node is set to 0x000003=3 (rising edge trigger), and the type code is 06.

  • Example 1: Downlink Payload: 06000000      --->  AT+INTMOD1=0
  • Example 2: Downlink Payload: 06000003      --->  AT+INTMOD1=3
  • Example 3: Downlink Payload: 06000102      --->  AT+INTMOD2=2

0
OK

  Downlink Command: 0x34

0X0A 01    // Same as AT+IMAGE=1

0x0A 00    // Same as AT+IMAGE=0

No downlink commands for feature

3.2.5 Uplink log query

Feature: This command can be used to query upstream logs of data packets.

AT Command: AT+GETLOG

Command ExampleFunction
AT+GETLOG  

Downlink Command: 

No downlink commands for feature

4. Clock logging

Sometimes when we deploy lots of end nodes in field. We want all sensors sample data at the same time, and upload these data together for analyze. In such case, we can use clock loging feature.

We can use this command to set the start time of data recording and the time interval to meet the requirements of the specific collection time of data.

  • AT Command: AT+CLOCKLOG=a,b,c,d

a: 0: Disable Clock logging.   1: Enable Clock Logging

b: Specify First sampling start second: range (0 ~ 3599, 65535)         // Note: If parameter b is set to 65535, the log period starts after the node accesses the network and sends packets.

c: Specify the sampling interval: range (0 ~ 255 minutes)

d:How many entries should be uplink on every TDC (max 32)

image-20240315141254-1.png

Example:

AT+CLOCKLOG=1,65535,1,5

After the node sends the first packet, data is recorded to the memory at intervals of 1 minute. For each TDC uplink, the uplink load will include: battery information + the last 5 memory records (payload + timestamp).

Note: Users need to synchronize the server time before configuring this command. If the server time is not synchronized before this command is configured, the command takes effect only after the node is reset.

12. Appendix I: Field Installation Photo

Step1:

Find a water meter, install the AIS Sensor on the water meter fixture and install it on the water meter

The following is a comparison of before and after installation:

image-20240801091742-1.png

Note: When the ambient brightness is too high, you can use a cover (such as cardboard) to block other light sources (such as the sun, electric lights) to prevent light reflections from causing the AIS sensor to read inaccurate values.

Step2:

Calibrate the AIS Sensor so that it can accurately read the water meter value.

Get image data

When 0A 01 is sent on the TTN platform, the device will execute the command to send image data packet after sending the next data packet.
