Size Diagram:
The adjustable resistor on the amplifier module can adjust the threshold value continuously, and the sensitivity can be continuously adjusted from slight pressure trigger to heavy pressure trigger.
The amplifier module kit outputs a high level when it is not pressed, and outputs a low level when the pressed pressure reaches the threshold signal.
The kit is not easily interfered by external electromagnetic noise, and can be used in various occasions with strong interference;
The signal frequency band of this kit is about DC-10KHz. The power supply range is 2.8~9V, 5V is recommended;
Threshold adjustment: There are adjustable resistors on the board, and the trigger strength can be adjusted by adjusting the resistors.
Easy to integrate: The circuit board is extremely small and small. After the parameters are adjusted, the entire circuit board can be covered with heat-shrinkable sleeves and wires for free installation, or can be fixed with screw holes.

Note: This kit is suitable for switching applications and cannot output pressure values linearly; if you need to measure pressure, please refer to our other kit modules.
