The principle of the pressure sensor test is to apply the stress applied in the sensing area of the sensor film into the change of the two-line resistance value, and obtain the external stress change information according to the calibration curve of the stress-resistance. The greater the stress, the lower the sensor output resistance.
Scope of application
Can be used for geotechnical engineering triaxial test earth pressure test, sample pressure distribution test, bionic robot foot under the ground sensing, mammalian bite force test biological experiments and other industrial fields.
These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.
