Gravity: AI Vision Posture and Gesture Sensor

SKU: SEN0670

The Gravity: AI Vision Posture and Gesture Sensor is revolutionizing smart home control and interactive art with its ability to recognize and learn human postures and gestures without coding. Designed for robot interactions, this sensor supports two recognition modes—gesture and skeleton—and offers one-click learning for personalized interactions. Its low power consumption allows battery-powered and long-term use. With compatibility for micro:bit, Arduino, and ESP32, and support for MakeCode and Arduino IDE, it lowers the barrier for creators. The sensor processes data locally, ensuring privacy and fast response. Ideal for hobbyists, it addresses challenges like high entry barriers and complex model training, making personalized body interaction projects easy to implement.

    Pinout

    SEN0670-Pinout

    No. Name Function Description
    ① VCC Power Supply Positive (3.3~5.5V)
    ② GND Power Ground
    ③ C/R I2C Clock Line SCL / UART Receive Pin RXD (3.3V Logic Level)
    ④ D/T I2C Data Line SDA / UART Transmit Pin TXD (3.3V Logic Level)
    ⑤ WAKEUP Pull high to wake up the sensor, pull low to enter low-power mode. Used to control the operating state on demand and reduce power consumption.
    ⑥ USB Type-C Interface 1. Connect to the configuration software to view the sensor's recognition image and recognition data.
    2. Connect to the configuration software to set up custom learned gestures and poses.
    ⑦ I2C/UART Communication Mode Selection Switch Factory default is I2C communication mode with slave address 0x3A. The sensor must be re-powered on after switching the communication mode.
