SenseCAP 1101 Vision AI sensor is a powerful edge device manufactured by our friend at Seeed Studio. One of its most advantageous features is that you can easily configure it by using SenseCAP Mate app, in which you can choose several different settings such as the Algorithm as well as the Model detection.
Requirements:
An active account on The Things Network
An active account on Ubidots
A cellphone running either Android or iOS with Bluetooth

1. Configure the SenseCap A1101
Please follow the steps given in this guide’s first section: “Configure the SenseCap S2100”
Once done, you can come back to this guide and go further the next section
You can select the algorithm as well as the model that the sensors detects
For this article, the Object Detection algorithm was chosen and the AI model was set to Human Body Detection, however, if you want to change these settings, you can do so.
Pro Tip: You can also train your own model. Refer to the following link for more information
2. Register the SenseCap A1101 on TTN LNS
Please follow the steps given in this guide’s second section “Register the SenseCap S2100 on TTN LNS”
Once done, you can come back to this guide and go further the next section
3. Create the Ubidots Plugin and Decoder
Go to your Ubidots account on the “Devices” tab and click “Plugins”
Create a new “The Things Stack” plugin
Leave the “Ubidots device type” on its default option if you wish, however, you can set any name for your device type
On “Ubidots Token” select "Default Token" or the token that you wish to use for this plugin
Click on the Arrow icon to go to the next step
Give the plugin a name and a description
Click the Check icon
Click on the recently created plugin to navigate to its options.
Search for the “Decoder” tab and copy the “HTTPs Endpoint URL”. This will be needed for further steps.
Scroll down to the “Decoding Function” section and paste the following code on the text field:
function format_payload(args){
var messages = args["uplink_message"]["decoded_payload"]["messages"];
var ubidotsPayload = {};
var varLabelMap =
{
4175:"AI-detection-1",
4176:"AI-detection-2",
4177:"AI-detection-3",
4178:"AI-detection-4",
4179:"AI-detection-5",
4180:"AI-detection-6",
4181:"AI-detection-7",
4182:"AI-detection-8",
4183:"AI-detection-9",
4184:"AI-detection-10"
};
messages.forEach(msg => {
if (msg.hasOwnProperty("measurementId")) {
ubidotsPayload[varLabelMap[msg.measurementId]] = msg["measurementValue"];
}
});
return ubidotsPayload;
}
module.exports = { format_payload };
