(inc VAT £23.40)Percussion knock sensor module for Arduino KY-031
Percussion knock sensor module for Arduino and other microcontroller projects
This module is a switch that will detect being hit, it is not as sensitive as the vibration switch (KY-002) so can be used in projects that may be moving and an impact needs to be detected. This sensor acts like a switch that will "make" when the sensor is knocked.
Voltage :upto 5VDC
Size 19x15mm
