Tilt Detector
The Tilt Detector is based on a 68HC908QT4 microcontroller.
The small detector can measure 360° of tilt and display the
result on its LCD, which is controlled by only two pins. The
tilt data is stored in the detector and can be displayed on
the screen. The detector can handle operations, or it can
send stored data to a PC. In order to improve the measurement
accuracy, the gadget can calibrate the sensor and save the
calibration parameters for better performance. It can also
measure acceleration in the range of –2 to +2 g. There are
two versions of the circuit: one is a digital version, which
is powered by an input capture function with high accuracy,
and the other is a low-cost analog version, which is powered
by the inner ADC.
