- PC ×1
Software Preparation
- Download CH340K Driver: CH340K Driver
- Download SEN0670_Upper Computer Software: SEN0670_Upper Computer Software
Wiring Diagram
Operating Steps
-
Download the SEN0670_Upper Computer Software, save it to a local folder, and unzip it. Locate the SEN0670-AI Posture and Gesture Sensor.exe file as shown in the image below.
-
Double-click the .exe file to open the host computer, and you will see the Upper Computer Software interface as shown in the image below.
| Function Name | Concise Description |
|---|---|
| Mode Switch | Toggles between Gesture Recognition and Posture Recognition modes. |
| Data Area | Shows gesture ("hand_keypoints": []) or posture ("pose_keypoints": []) data, with one-click copy support. |
| Learn Button | Learns and custom-names detected gestures/postures; max 8 custom gestures + 8 postures. |
| Clear Button | Erases all learned custom gestures/postures. |
| Set UART Baud | Set the serial port baud rate of UART interface to take effect in case of power failure. |
-
Click the port drop-down menu, select the matched serial port (e.g. COM27 (USB-SERIAL CH340K)), then click Open Serial Port → Connect Device to access the real-time camera feed and recognition data.
-
The Upper Computer Software defaults to the Gesture Recognition function. It will display the ID, confidence score, and 21 keypoint data of any detected gesture in real time.
-
Gesture Learning Steps: When the camera screen recognizes a custom gesture, click the Learn Button and keep the gesture stationary for 3~4 seconds until the learning is completed (the color of the gesture will change at this time).
After changing the gesture ID name, perform the learned gesture again and you will see that the ID in the camera recognition area changes to Rock.
-
There is no need to power off the sensor; simply click the Function Switch to directly switch to the Posture Recognition function. The posture recognition experience is shown in the image below.
-
The posture learning steps are the same as the gesture learning steps and will not be repeated here.
The optimal distance for gesture recognition is 50~60cm; the optimal distance for posture recognition is 2m.
Additional Information
If you encounter the problem of connecting the sensor to the PC and the upper computer does not display the CH340K serial port, the solution is as follows:
- View PC's Device Manager ->Ports (COM and LPT), and check if there is a serial port named CH340K.
- If not, then check if the CH340K serial port driver file is installed on the PC, please download and install it.
