The BMS31M002 has the same functions and specifications as the gesture recognition module (1D), BM32S3021-1. The difference between them is that the BMS31M002 breaks out the BM32S3021-1’s pins to match the BMCOM connectors and can directly connect to BMduino development boards, such as BM53A367A.
You can use the product with other development boards, such as Arduino UNO, as well.
The BMS31M002 includes two built-in infrared transmit LEDs and a sensor to measure the changes in light reflectance at each of the infrared transmit LEDs over time and turn those changes into gestures.
| Pin | Pin name | Function |
|---|---|---|
| 1 | INT | Gesture detected: output low
Non-detected: output high |
| 2 | RX | UART: RX |
| 3 | TX | UART: TX |
| 4 | VDD | Power supply: 3.0V to 5.5V |
| 5 | GND | Ground |
The BMS31M002’s sensing distance is 5 to 25cm, and it is configurable. Steps for learning distance:
