我可以使用LPS25HB来测量足中风的压力

你好，
这取决于其他情况，例如测量设备的物理设置。请注意，LPS25HB是一种气压传感器，因此需要加入某种气垫。您可以尝试将传感器放入一盒密封空气中（为了快速评估，请尝试带密封的塑料食品盒）。
下面的计算只是一个粗略的估计：
压力定义为每面积的力（p = F / A）。力被定义为重量乘以地球的重力常数（cca 9,8
米/秒^ 2
，但是，对于简单的计算，我们可以说10，这意味着F = m * g，对于一个常设的人来说。 F = 80 kg * 10 m / s ^ 2 = 800 N.一英尺的区域（在跑步过程中只有一个被踩到）可能是1 dm ^ 2，这意味着如果你踩到一个内部有大气压力的盒子，用一只脚，你可以增加压力p = F / A = 800 N / 0,01平方公尺= 80 000 Pa。
该传感器的范围仅为25 000 - 125 000 Pa，大气压力为cca 100 000 Pa，因此踩在箱子上会产生大约180 000 Pa，超出范围。

Hello,
It depends on other circumstances, for example physical setup of your measurement device. Please note that LPS25HB is an air pressure sensor, so some kind of air 'cushion' needs to be incorporated. You could try putting the sensor into a box of sealed air (for quick evaluation, try a plastic food box with a sealing).
The calculation below is just a rough estimation:
Pressure is defined as force per area (p = F / A). Force is defined as weight multiplied by earth's gravity constant (cca 9,8
m/s^2
, but let's say 10 for simplier calculations), meaning F = m * g, for a standing person ca. F = 80 kg * 10 m/s^2 = 800 N.Area of a foot (only one is being stepped on during a run) could be 1 dm^2, which means if you step on a box with atmospheric pressure inside, with one foot, you could increase the pressure by p = F / A = 800 N / 0,01 m^2 = 80 000 Pa.
The range of this sensor is just 25 000 - 125 000 Pa. and the atmospheric pressure is cca 100 000 Pa, so stepping on the box will give you about 180 000 Pa, which exceeds the range.

还有一些想法：
一个或多个称重传感器可以告诉您重量。看看这篇文章：

 。但是，要确定压力，您必须知道足部区域。这意味着为了确定施加在脚上的压力，您需要先测量脚。您还可以使用加速度计来了解人的跑步速度。要么将它们放在鞋子里，要么放在跑步带内。

A few more ideas:
One or more load cells could tell you the weight. Have a look at this article:
https://learn.sparkfun.com/tutorials/getting-started-with-load-cells
. However, to determine pressure, you would have to know the foot area. This means in order to determine a pressure applied to your foot, you need to measure the foot first.You could also use an accelerometer to get the idea how rapidly is a person running. Either put them in shoes or inside a running belt.
