Flex Sensor to bargraph monitor using PIC16F886
- Rajkumar Sharma
Tiny Bar-Graph display provides a Red color bright, easy to read display which is proportional to the force applied on the FLEX sensor surface. This Bar-Graph has 20 segments in a single color and display Force applied on the FLEX sensor. The Barograph force monitor is based on a 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- a jumper for output set point, which can be configured for output control, alarm, Relay.
Force sensing resistors are polymer think film devices which exhibit 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.
