This basic piezo sensor can be used in
anti-theft devices, electronic locks, mechanical equipment vibration detection,
and detection range bull's-eye counts vibration testing occasions. A simple
resistor should get the voltage down to ADC levels. These ADC levels could be
given to any controller/processor and necessary decisions could be taken
through it.
Features
- Sensitivity adjustable.
- The vibration detection has no direction.
- With analog, digital and TTL level output signal.
Applications
·
Vibration analysis
·
Shock detection and event capture
·
Condition monitoring
Using The Sensor
- Connect +5v to pin 2 and ground to pin 5 and 6.
- Pin 4 and 5 should be connected to particular transmitter and receiver pin of controller.
- Output pin may be connected to any port pins and can be used to any application.
Working
Digital
vibration sensing in the ADIS16220 starts with a wide- bandwidth MEMS
accelerometer core that provides a linear motion-to-electrical transducer
function. Figure 6 provides a basic physical diagram of the sensing element and
its response to linear acceleration. It uses a fixed frame and a moving frame
to form a differential capacitance network that responds to linear
acceleration. Tiny springs tether the moving frame to the fixed frame and
govern the relationship between acceleration and physical displacement. A
modulation signal on the moving plate feeds through each capacitive path into
the fixed frame plates and into a demodulation circuit, which produces the
electrical signal that is proportional to the acceleration acting on the
device.
