Mikroe Vibra Sense 2 Click has a piezo sensor suitable for vibration measurements. The board features the TE Connectivity Measurement Specialties LDT0-028K flexible 28μm thick piezoelectric PVDF polymer film. It has screen-printed silver ink electrodes, laminated to a 0.125 mm polyester substrate, and fitted with two crimped contacts. The sensing element of the LDT0-028K comprises a cantilever beam loaded by an additional mass to offer high sensitivity at low frequencies. This board is ideal for vibrating sensing applications, security systems, body movement, and more.
