Introduction

The EVAL-ADXL345Z-S is a low-cost evaluation board specifically designed to evaluate the performance of the Analog Devices ADXL345Z-S accelerometer, which is a 3-axis, low-g iMEMS (Integrated Micro-Electro-Mechanical Systems) accelerometer that is capable of measuring up to 5 g. This evaluation board is intended to provide a convenient platform for design engineers to experiment with the features of the ADXL345Z-S accelerometer. The evaluation board uses a 0.1” pitch connector and can be connected to other boards or devices connected to “breadboards” or custom designs.

Application Field

The ADXL345Z-S features a variety of different operating modes and has a low power consumption. It is ideal for applications in consumer electronics, particularly for measuring display orientation, vibration analysis, and vehicle motion tracking. It can be applied in many different industries for gaming, sports, and health monitoring. The evaluation board is also well-suited for educational purposes, allowing students and teachers to gain hands-on experience with the ADXL345Z-S accelerometer.The evaluation board is capable of providing various levels of data transmission, including raw acceleration and tilt angle output, as well as an interrupt output which can be configured with a variety of sensor-specific parameters.

Working Principle

The ADXL345Z-S is a low-g accelerometer that is powered by a single 1.8 V supply and operates in a temperature range of -40°C to +85°C. It utilizes capacitive transduction which detects the change in capacitance as the acceleration changes, making it a MEMS device. The evaluation board\'s circuit is designed to optimize the performance of the ADXL345Z-S accelerometer by offering a low-noise and low-power signal conditioning which amplifies and filters the raw acceleration output signal.The ADXL345Z-S simultaneously samples the acceleration along three axes (x, y, and z) in order to measure gravity. The acceleration data is then processed through a 14-bit analog-to-digital converter which converts the signal into a digital output. The ADXL345Z-S can be configured in two modes, free-fall and motion detection. In order to accurately measure the acceleration, the evaluation board employs temperature compensation which can be adjusted using the settings on the board.
