ADXL335 GY-61 Triple Axis Accelerometer Module

ADXL335 GY-61 Triple Axis Accelerometer Module Overview

The ADXL335 GY-61 is a compact 3-axis accelerometer module designed to deliver reliable, analog acceleration measurements across the X, Y, and Z axes. With a ±3g measurement range and high sensitivity, this module is ideal for prototyping and production projects that need accurate motion sensing with minimal power draw.

Key Features

• Triple-axis sensing: Simultaneous X, Y and Z acceleration outputs for complete 3D motion tracking.
• Analog voltage outputs: Each axis provides an analog voltage proportional to acceleration for easy interfacing with ADC inputs.
• High sensitivity: Detects subtle vibrations and dynamic movements with good resolution.
• Wide ±3g range: Captures both gentle motions and higher-impact events.
• Low power: Efficient operation suitable for battery-powered and portable devices.
• Compact form factor: Lightweight and small footprint for embedded and wearable applications.

Typical Module Pins and Connectivity

• VCC — Power supply input (check your module documentation for recommended voltage)
• GND — Ground
• X — Analog output for X-axis
• Y — Analog output for Y-axis

Integration Tips and Best Practices

• Use a stable power supply and place a 0.1uF decoupling capacitor close to VCC and GND to minimize noise.
• Connect outputs to a microcontroller ADC with adequate resolution and sample rate for your application.
• Calibrate zero-g offsets for each axis in software to improve accuracy over temperature and manufacturing tolerances.
• Apply simple low-pass filtering in hardware or software to reduce high-frequency noise and vibration spikes.
• Securely mount the module to avoid mechanical resonance that can distort readings.
