DESCRIPTION
The SQ-SEN-200 series sensor acts like a normally closed
switch which chatters open and closed as it is tilted or vibrated.
Unlike other rolling-ball sensors, the 200 is truly an
omnidirectional movement sensor. It will function regardless of
how it is mounted or aligned.
When at rest, it normally settles in a closed state. When in
motion, it will produce continuous on/off contact closures. It is
sensitive to both tilt (static acceleration) and vibration (dynamic
acceleration). The sensor can be easily used to produce a series
of CMOS or TTL level logic level or pulse train using a single
resistor to limit current. The signal level can be read directly by
a digital input. This can be used to interrupt (wake up) a
microcontroller or can be counted to estimate the amount and
duration of activity. The sensor is fully passive, requires no
signal conditioning, and draws as little as 0.25uA of continuous
current.
