是否可以使用LPS25HB绝对压力传感器作为力传感器

你好，
如果你想测量体重，我会考虑使用称重传感器：

 LPS25HB是一种气压传感器，内部有一层精致的膜，因此我不建议将其放入任何其他材料中。但是，您可以尝试将传感器嵌入某种气垫或盒子中，并在对盒子施加压力后测量气压变化。然而，这不仅对施加的力敏感，而且对温度变化敏感。除此之外，您需要小心不要破坏传感器的膜，它很容易超出压力边界。 （如果您将传感器放在密封良好的便当盒中并在盒子上施加压力或改变环境温度，您可以试试这个。）

Hello,
If you are trying to measure weight, I would consider using a load cell:
https://learn.sparkfun.com/tutorials/getting-started-with-load-cells
LPS25HB is constructed as an air pressure sensor and has a delicate membrane inside, so I wouldn't recommend putting it into any other material. However, you can try to embed the sensor into some kind of an air pillow or box and measure the air pressure change after applying pressure to the box. However, this is sensitive not only to applied force, but also to temperature changes. In addition to that, you need to be careful to not break the sensor's membrane, it is very easy to get outside the pressure boundaries. (You can try this if you put the sensor in a well sealed lunch box and applying pressure on the box, or changing the temperature of the environment.)

我只记得一个较旧的问题，我提供了一个估计，以了解通过踩在带有压力传感器的密封盒内可以产生多少压力：

I just remembered an older question where I provided an estimate to get the idea of how much pressure can be generated by stepping on a sealed box with a pressure sensor inside:

亲爱的大卫，
谢谢您的回复。我想知道，如果将整个传感器密封到聚合物中，它自己的感应室是否可以作为你提到的密封盒。

Dear David,
Thank you for your reply. I was wondering if, sealing the whole sensor into the polymer, its own sensing chamber could act as the sealed box you mentioned.
