Fermion: GR10-30 Gesture Recognition Sensor

SKU: SEN0543

The GR10-30 gesture sensor recognizes 12 hand gestures: up/down/left/right, forward/back, clockwise/counterclockwise (continuous), hover, and wave. Users adjust parameters (distance, rotation angle, hovering time, window size) for accuracy. It offers stable, high accuracy up to 30cm, with two interrupt pins (gesture trigger, object entry). Ideal for non-contact apps: gesture remotes, robot interaction, HMI, lighting control, gesture games.

    FAQ

    • I'm using a dev board with an ESP32­-PICO-­MINI-­02. The I2C pins on this dev board are SDA=22 and SCL=20

      Even when specifying these I2C ports in line 48 of DFRobot_GR10_30.cpp: _pWire->begin(22,20); the board fails to initialize, presumably because the ESP32 can't find it on the I2C bus.

      All works fine on an Arduino MKR WiFi 1010 whose I2C pins default to SDA=11, SCL=12

      How can I define the I2C pins?

      Solved. It was a wiring problem. The sensor and its library work just fine.
