Outline
The 3-axis acceleration sensor module WACOH-TECH is a modular product of a 3-axis acceleration sensor made by semiconductor technology and micromachining technology and contained in a case, from which output wiring is led out in cabling. This one sensor module can detect three axes (Ax, Ay, and Az) simultaneously. Since the 3-axis acceleration sensor is mounted on the board in the case, outputs can be easily checked by simply connecting the protruding wiring to measuring equipment, etc.
It can be used for a wide range of applications, such as the first use of an acceleration sensor or immediate testing.
Applications
- Testing of airbag system
- Vibration measurement and control
- Seismometers (seismoscopes), (crime preventive vibration sensors)
- Robot arm control
- Fall detection testing, pedometers
