Piezoelectric Sensor Description Piezoelectric sensors use quartz crystals to convert electrical energy into sound. When a voltage is applied, the crystal expands and contracts, ge nerating sound frequencies. These sensors also operate in reverse: pressure or sound waves distort the shape of the quartz crystal, producing electrical energy. This generated electrical energy can be stored and harnessed using batteries and capacitors. Features High sound output and input capability Suitable for DIY applications Ideal for use as musical instrument sensors Specifications Specification Value Dimensions 27 mm Supply Voltage 3 V Tone Type Diaphragm Resonant Frequency 0.5 KHz Capacitance 25 nF Temperature Range -30 to 70 degrees Thickness 0.35 mm Lead Wire Size 10 cm (100 mm) Each device is fully inspected and supplied with 100 mm leads fitted.
