Força & Pressão & Vibração
This is a force sensitive resistor with a square, 1.75x1.5", sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance.
This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.
This straight bar load cell (sometimes called a strain gauge) can translate up to 10kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to, and proportional of, the strain (e.g. pressure or force) applied to the bar.
Electronic brick of tilt switch can be connected to analog I/O port and used in tilt sensor for smart car or robot. When the sensor is in the horizontal position, the output is high level; when the sensor rotates counterclockwise to form an angle of more than 15 ° with the horizontal line, the output is low level.
