1. Product Introduction
1.1 Overview
SenseCAP A1101 LoRaWAN Vision AI Sensor combines TinyML AI technology and
LoRaWAN long-range transmission to enable a low-power, high-performance AI
device solution for both indoor and outdoor use.
This sensor features Himax's high-performance, low-power AI vision solution which
supports the Google TensorFlow Lite framework and multiple TinyML AI platforms.
Different models can implement different AI functions, for example, people counting,
object recognition, meter recognition, etc. Users are able to adopt models provided by
native firmware, or train and generate their own models through AI training tools, or
procure deployable, commercial models from third-party model providers.
With the IP66 rating, -40 ~ +85C ° operating temperature, built-in 19Ah high-capacity
battery and devices’ low power consumption, the A1101 sensor can operate in harsh
outdoor environments for up to 10 years with a range of up to 10km. The built-in
Bluetooth facilitates setup and greatly reduces large-scale deployment costs. Users
can focuson application development with the easyset-up and start retrieving data in

Platform
Description
SenseCAP for The
Things Network
It must be used with SenseCAP Outdoor Gateway
(https://www.seeedstudio.com/LoRaWAN-Gateway-EU868-p-
4305.html ). SenseCAP builds a proprietary TTN server that
enables sensors to be used out of the box when paired with an
SenseCAP outdoor gateway.
SenseCAP for Helium
Default platform.
When there is the Helium network around the user, data can be
uploaded using sensors. Devices run on a private Helium console
of SenseCAP. Users do not need to create devices on Helium
console, right out of the box.
Helium
Connect Sensor to public Helium console.
The Things Network
Connect Sensor to your TTN(TTS) server.
Other Platform
Other LoRaWAN Network Server.
1) SenseCAP for Helium:
We provide the SenseCAP Portal to manage devices and data:sensecap.seeed.cc
We built a private Helium Console with an embedded SenseCAP Portal. When users
get the SenseCAP sensors, you can use it by scanning the code and binding it to the
Portal.

IoT into the Wild
14
“SenseCAP for Helium”is selected by default. The device runs in a fixed main
frequency and sub-band, refer to Helium Frequency Plan
(https://docs.helium.com/lorawan-on-helium/frequency-plans/ ). You only need to
select the main frequency, such asEU868 and US915.
SenseCAP for Helium supports the following frequency plan:
EU868 / US915 / AU915 / KR920 / IN865 / AS923-1 / AS923-2 / AS923-3 / AS923-4
2) SenseCAP for TheThings Network
SenseCAP Portal also builds the TTN private server, and the sensor mustbe used
together with the SenseCAP Outdoor Gateway
(https://www.seeedstudio.com/LoRaWAN-Gateway-EU868-p-4305.html) or
SenseCAP Multi-Platform LoRaWAN Indoor Gateway
(https://www.seeedstudio.com/SenseCAP-Multi-Platform-LoRaWAN-Indoor-
Gateway-SX1302-EU868-p-5471.html).
SenseCAP Multi-Platform LoRaWAN Indoor Gateway supports the following
frequency plans:
IN865 / EU868 / RU864 / US915 / AU915 / KR920 / AS923.
3) Helium
Users can choose sensors to use on the public helium console:
https://console.helium.com/
4) The Things Network
Users can choose sensors to use on the public The Things Network server:
https://console.cloud.thethings.network/
5) Other Platform:
When you use other LoRaWAN network server, please select Other Platform.

15
At this point, you need to determine the sensor frequency band according to the
gateway frequency and sub-band.
A1101 Sensors support the following frequency plan:
Sensor Frequency

Note1:
Different countries and LoRaWAN network servers use different frequency plans.
For Helium network, please refer to:
https://docs.helium.com/lorawan-on-helium/frequency-plans
For The Things Network, please refer to:
https://www.thethingsnetwork.org/docs/lorawan/frequency-plans/
Note2:
1) When using the SenseCAP platform, the EUI, APP EUI and APP Key are fixed
and are the same as the sensor label.

IoT into the Wild
16
2) When the sensoris selected to be used with a public platformsuch asHelium or
TTN, the EUIwill not change,and the sensor will generate a new fixed App EUI
and App Key for network access.
5.3.2 Set the Interval
