在哥斯达黎加 OSA 半岛森林砍伐地区工作的研究人员决定并放置这些栖息箱以吸引快速驱散的蝙蝠，从而加快重新造林的速度。

The sensor sits in the knob of the company's so-called Smart Bat and uses two accelerometers and a three-axis gyroscope to measure bat speed, hand speed, attack angle and other factors.

该传感器位于这家公司智能球棒的把手处，其中的2个加速器及一个3轴陀螺仪能够对球棒速度、手速、打击角度等其他因素进行测量。
