Tiny Bar-Graph display provide a Red color bright, easy to read display which is proportional to the force applied on FLEX sensor surface.  This Bar-Graph has 20 segments in single color and display Force applied on FLEX sensor. The Barograph force monitor is based on PIC microcontroller with 10 Bit resolution ADC.  This high performance measurement provides unique capabilities and can be used in various applications. Each LED output provided with Solder- jumper for output set point, which can be configured for output control, alarm, Relay.

Force sensing resistors are polymer think film devices which exhibits a decrease in resistance with an increase in the force applied to the active surface. Its force sensitivity is optimized for use in human touch control of electronic devices.

Note: Board is provided with Trim-Pot for fine tuning of display.
