Dear sensor enthusiasts, our sensor has a maximum resistance of 800mm. If a longer length is required, we will achieve the length you want by docking, but the resistance can only reach the original resistance of 800mm. After docking, the product can be used normally, please confirm that it can be accepted before purchasing, thank you

By selecting a suitable fixed resistor, the pressure and output voltage can be approximated to a certain degree in a certain pressure range.

When the force is so large that the sensor resistance is less than R1, the voltage comparator U1+ is higher than the U1-output high level. The high level of the output can provide trigger signals for additional devices such as an external relay to control the switch, and thus control the LED light, buzzer alarm motor and other load devices.
