Now, we will tilt the accelerometer sensor or the material to which the sensor is attached in different direction and we will see the changes in its output values in the 16×2 alphanumeric LCD. So, first it will convert the three analog outputs of ADX元35 accelerometer sensor to digital values using its analog to digital converter and then it will display the three converted digital values in the 16X2 alphanumeric LCD.
Try to move the sensor slowly in all the directions and observe the readings. Then open Serial monitor and you will see acceleration readings in x, y, z-axis as shown below. Finally, connect the ADX元45 sensor with Arduino UNO properly and upload the code in the Arduino Uno board. But, the three outputs of 3-axis accelerometer sensor are analog in nature and microcontroller cannot process the analog signal directly. Testing ADX元45 accelerometer Arduino Interfacing. Here, we will measure the tilt of the accelerometer sensor or the material to which the accelerometer sensor is attached and we will display the three outputs of accelerometer sensor in a 16X2 alphanumeric LCD. In this project, we will learn How to interface a 3-axis accelerometer sensor-ADX元35 with AVR ATmega32 microcontroller. The ADX元35 accelerometer sensor gives three analog output values which correspond to three coordinate axes: – x-axis, y-axis and z-axis values.
The analog outputs are ratio metric: that means that 0g measurement output is always at half of the 3.3V output (1.65V), -3g is at 0V and 3g is at 3.3V with full scaling in between. The accelerometer sensor is used in mobile devices, gaming systems, disk drive protection, image stabilization, sports devices, health devices and etc. ADX元35 accelerometer sensor is a MEMS (Microelectromechanical systems) sensor which can measure static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion, shock, or vibration.
