Summary of ADXL05 DIĞITAL INCLINOMETER CIRCUIT PIC16F84

This project implements a digital inclinometer using a PIC16F84 microcontroller. An ADXL05 accelerometer senses inclination (0.0–89.9°), an AD7896 12-bit ADC digitizes the signal, and the PIC processes data and drives 7-segment displays via a 74HC164 serial-to-parallel shift register. VR1 and VR2 provide gain and offset adjustments. Assembly source, schematic, and PCB files are provided.

Parts used in the DIĞITAL INCLINOMETER PIC16F84 Project:

  • PIC16F84 microcontroller
  • ADXL05 accelerometer
  • AD7896 12-bit serial ADC
  • 74HC164 serial-to-parallel shift register
  • 7-segment display(s)
  • VR1 gain adjustment potentiometer
  • VR2 offset adjustment potentiometer
  • PCB (schematic and PCB files provided)
  • Supporting passive components (resistors, capacitors)
  • Power supply components

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.
