The Device To start off I needed to gear up an adaptive shock/vibration sensor switch to test out some ideas. I don’t like to use discrete components, so I got a little lazy started a lengthy Google ...

In conclusion The SW-420 vibration sensor module works well to detect even feeble impacts. The digital output is helpful in cases where you only need to know when it has reached a specific level. In ...

Circuit and Working Fig. 2 displays the circuit diagram of the standalone shock and vibration sensor device. It is built around transistor 2N2222 (T1), two electrolytic capacitors: one of 10μF, 16V ...

Now the HS35R vector-duty encoder, a newly redesigned hollow-shaft rotary encoder from Dynapar Corp., Gurnee, Ill., stands up to a 400 g shock load with a disc made of hard plastic instead of glass.

In addition, the shock sensor has the ability to prevent theft as it automatically locks your LifeBook when sudden movement is detected. Without your Microsoft Windows log-in password, the next user ...
