Grove - Piezo vibration sensor LDTM-028K

Grove - Piezo vibration sensor

The Grove piezo vibration sensor is suitable for measuring strain, vibration, shock and touch. The module is based on the PZT film sensor LDT0-028K. LDTM-028K is a vibration sensor where the sensing element consists of an external cantilever loaded by an additional mass to provide high sensitivity at low frequencies. When the sensor moves back and forth, the voltage comparator inside generates a certain voltage. A wide dynamic range (0.001 Hz ~ 1000 MHz) guarantees excellent measurement performance. And you can adjust the sensitivity by adjusting the integrated potentiometer.

Features

• High sensitivity to strong shocks: With the help of the LDT0-028K PZT foil sensor, you no longer have to worry about sensor damage from large shocks when measuring strain, vibration, impact and touch.
• Wide dynamic range: Detectable range of up to 0.1 Hz to 180 Hz, making this sensor more suitable for measuring various applications.
• Easy sensitivity adjustment: Adjust the sensitivity of the built-in potentiometer by adjusting the screw.
• Grove unit plug-in system: The sensor ensures "plug and play" and can be used for various applications.
