Configuring Model Output and GPIO on SenseCraft AI for XIAO ESP32S3 Sense
This wiki article provides a step-by-step guide on how to configure model output and GPIO settings for the XIAO ESP32S3 Sense board using the SenseCraft AI platform. By following these instructions, you will learn how to trigger GPIO level changes based on specific event conditions detected by your trained model.
Prerequisites
Before you begin, ensure that you have the following:
- XIAO ESP32S3 Sense board
- USB-C data cable
- Expansion Board Base for XIAO with OLED
- Grove LED

Step 1. Access the SenseCraft AI Vision Workspace and connect the XIAO ESP32S3 Sense
Open your web browser and navigate to the SenseCraft AI Vision Workspace page.
Select the XIAO ESP32S3 Sense board from the available devices.
Using the USB-C cable, connect your XIAO ESP32S3 Sense board to your computer. Once connected, click the Connect button located in the top-left corner of the SenseCraft AI Vision Workspace page.
Step 2. Ensure a Model is Loaded on the XIAO ESP32S3 Sense
Before proceeding, make sure that your XIAO ESP32S3 Sense board has a trained model loaded. If you haven't loaded a model yet, refer to the SenseCraft AI documentation on how to train and deploy models to your device.
If you want to use your own trained model, you can refer to the following two Wikis.
Step 3. Configure GPIO Output
In the left sidebar of the Vision Workspace page, click on the Output option. From the available output options, select GPIO to access the GPIO configuration settings.
On the right side of the page, click the Trigger action when event conditions are met button.
A dialog box will appear, prompting you to input various parameters that will serve as the trigger conditions for changing the GPIO level. These parameters include:
Object: Specify the object that your model should detect to trigger the GPIO level change. For example, "face" if you want the GPIO to change when a face is detected.
Condition: Choose the condition that must be met for the trigger to occur. Options include "Greater than", "Less than", "Equal to", etc. For instance, selecting "Greater than" means the GPIO will change when the detected object's confidence level is greater than the specified value.
Confidence: Set the minimum confidence level required for the object detection to trigger the GPIO change. This value ranges from 1 to 100, with 100 being the highest confidence.
GPIO: Select the specific GPIO pin on the XIAO ESP32S3 Sense that you want to control. Available options include GPIO1(DO), GPIO2(D1), etc.
Default Status: Choose the default state of the selected GPIO pin. Options include "Low Level" and "High Level".
Active Status: Specify the state that the GPIO pin should change to when the trigger conditions are met. Options include "Low Level" and "High Level".
After configuring the desired trigger conditions, click the Confirm button to save the settings. Finally, click the Send button to transmit the GPIO trigger command to your XIAO ESP32S3 Sense board.
The XIAO board will now execute the command, and you can observe the effect on the connected Grove LED via the Expansion Board Base for XIAO with Grove OLED.
Keep in mind that the GPIO output functionality relies on the web-based connection between the SenseCraft AI platform and your XIAO ESP32S3 Sense board. If the connection is lost or interrupted, the GPIO level changing feature based on model detection will stop working. Ensure a stable connection throughout the process.
Conclusion
By following this step-by-step guide, you have learned how to configure model output and GPIO settings on the SenseCraft AI platform for the XIAO ESP32S3 Sense board. You can now trigger GPIO level changes based on specific event conditions detected by your trained model. This functionality opens up a wide range of possibilities for creating interactive projects and applications using the XIAO ESP32S3 Sense and SenseCraft AI. Remember to maintain a stable connection between the web platform and your device for seamless operation.
