测量身高是非常困难的, 因为孩子不能长时间静坐。
因此, 我们以低廉的价格找到了一个高精度传感器, 所以我们创建了一个不占用空间和时间的高度测量仪器。

部分

Distance sensor VL53L0X

It is a sensor of the resolution 1mm in a great wide range!The library for Arduino is below.

6 axis motion sensor MPU6050

3-axis gyroscope and 3-axis accelerometer can sensing posture information.This time, we use horizontal x-axis and y-axis acceleration to measure the level of the measuring instrument.But it’s a mess!The library for Arduino is located below (using mpu6050 and I2cdev).

when the measuring instrument is non-horizontal, it is red, and when it is horizontal, it glows green.

测量仪器

距离传感器 vl53l0x 被放置在盒子的底部。该传感器可以测量高达2米的距离, 分辨率为1毫米。

将微机 arduino nano 和6轴运动传感器 mpu6050 放入机箱中, 电源采用9v 电池。

MPU6050 用于测量加速度的 x 轴和 y 轴, 以检测水平方向。当测量水平时, led (nepipxel) 为绿色。当非水平为浅红色时。

距离显示在 lcd 显示屏上。

如何使用

液晶显示

普通模式

打开电源开关, 测量在正常模式下运行。在正常模式下, 测量距离始终显示在 lcd 上。当测量水平为水平时, 指示灯为绿色。当非水平为浅红色时。

测量模式

当你按住梅拉斯的时候。按钮 (键开关), 它将是测量模式。把尺寸放在头上。打开测量模式。当检测到水平状态下的距离时, led 为蓝光, 并保持测量值。

再次按下测量按钮, 恢复到正常模式。
