Diğital Inclinometer PIC16F84 Project
Inclino meter The analog signal is sampled by an Analog Devices AD7896 12 bit, serial analog to digital converter. The PIC receives digital data from this device and performs some conversions on the data so that it can display the result on the 7 segment displays. A 74HC164 serial to parallel decoder is used because the PIC does not have enough pins spare to drive the 8 display segments seperately.
The circuit uses an ADXL05 Accelerometer to sense the inclination angle. In this particular arrangement, it can read from 0.0 to 89.9 degrees. VR1 provides a small amount of Gain adjustment, while VR2 provides an Offset adjustment which can be used to ‘zero’ the reading.
