Shock
Figure 1 shows the configuration of G-Force sensor amplifier.
The shock sensor is connected between the pins 1 and 16.
How to output 0 or 1 from the pin 7 to detect whether there is a shock or not. !
a. Setting gain: C1
b. Setting the frequency (Hz) of HPF: Setting C3 (PF), R1 (k:)
c. Setting the frequency (kHz) of LPF: Setting C4 (pF), R2 (k:)
