Voice and vision module based on ESP32S3

Use ESP32S3 to develop a general module with speech recognition and visual recognition functions. It is mainly used for education, science and technology competitions, and creative design of DIY enthusiasts. The interface and functions are compatible with OpenMV, and its IDE can be used as development and debugging software. Most of the overall hardware design is compatible with ESP32S-EYE, so with a little adjustment of the interface definition, it can be compatible with ESP-WHO. ESP-WHO provides examples such as face detection, face recognition, cat face detection and gesture recognition, thus making this software The module is very playable.

Intelligent desktop interactive robot based on eps32s3

This design is an intelligent desktop interactive robot. As the name suggests, it is an intelligent robot that can interact with people. A 2.4-inch LCD screen is used as an important channel for human-computer information interaction. It also has voice recognition and sound playback functions, making contactless interaction more convenient. The interface design adopts the open source LVGL 8 GUI framework and uses ESP32S3 as the main control chip. The current regional temperature can be displayed on the interface, and the sound can be broadcast through voice interaction. It also displays the dynamics of the EEWORLD forum, including the display of the daily number of posts and the total number of posts. Through voice interaction, the voice broadcast of the total number of posts can also be obtained. . And the onboard LED lights can be controlled by voice.

Contactless face recognition access control system

In the epidemic environment, people don't want to touch things outside, so we create a face recognition access control system that does not require contact. When it is detected that a person is approaching the door, the face recognition device is awakened to save power consumption. When the face recognition passes, the door is controlled to open.
