LPRS (Low Power Radio Solutions) Q-EBT320 Piezo Bimorph Vibration Sensor

LPRS (Low Power Radio Solutions) Q-EBT320 Piezo Bimorph Vibration Sensor is a self-sustaining Low-Frequency Sensor (LFS) that uses multiple cantilever-type piezoelectric bimorphs with different resonant frequencies. This vibration sensor is a versatile low-power electromechanical transducer with the potential to convert mechanical or acoustic energy to electrical energy. The Q-EBT320 sensor operates at 100Hz frequency, 750pF±20% electrostatic capacity, -15°C to 55°C temperature range, and 50MΩ minimum (@50VDC) insulation resistance. This Piezo Bimorph vibration sensor is moisture-resistant and non-magnetic and comes in 15mm x 1.5mm x 0.6mm dimensions.
