The BMS81M001 detects a shake movement through the gyroscope and accelerometer within the MPU-6050. It is flexibility to configure the trigger parameters for shakes, including the threshold and duration. Once it is triggered, the STA pin changes from high level to low level, simultaneously the on-board LED lights up.
Furthermore, you can configure the standby mode active time when no shakes are detected.
There is a BMCOM on the product to directly connect to BMduino development boards, such as BM53A367A. You can use the product with other development boards, such as Arduino UNO, as well.
