This kit is not a single switch function. The magnitude of the analog OUT output amplitude and the force of the sensor have a linear output relationship; TTL output is 0.6*VCC window comparison output.
Multifunctional in one.
It supports lower voltage working voltage, and can supply power as low as 2.8V, which is more convenient for low-voltage operation occasions such as batteries~!
Definition of the four-core terminal of the signal amplifier module:
VCC+: power supply, +2.8~9V;
TTL: Comparator output terminal; comparison voltage is 0.6*VCC; output is TTL square wave
OUT: output signal terminal;
GND: Power ground.
Signal input terminal: Connect to PVDF sensor or other piezoelectric signal input
The adjustable resistor on the signal amplification module can adjust the amplification factor, ranging from 1 to 100 times. When 5V power supply, the signal amplifier module kit outputs about 2V level when there is no vibration, and outputs positive and negative fluctuating level signals when there is vibration. The picture shows the output waveform of tapping the PVDF.
This kit is a very weak signal measurement application, and it is very susceptible to interference from surrounding electric field signals. It needs to be as far away as possible from the interference source during use.
The signal frequency band of this kit is 0.5Hz-30KHz. The power supply range is 2.8~9V.
This kit is a general measurement test application, suitable for ordinary experimental teaching and simple measurement. If it is scientific research, engineering, research direction, it is recommended to refer to our VK10X series of high-precision charge amplifiers:
