ADXL345 3-Axis Accelerometer Module | Digital Tilt Sensor
ADXL345 3-Axis Digital Accelerometer Sensor Module
The ADXL345 is a low-power, 3-axis digital accelerometer that measures acceleration with selectable ranges from ±2g to ±16g. It communicates over I2C or SPI, making it easy to integrate with popular microcontrollers. Ideal for tilt detection, vibration analysis, and motion‑triggered projects.
Key Specifications

| Communication Interface | I2C (0x53 default) and SPI |
| Acceleration Range | ±2 g, ±4 g, ±8 g, ±16 g (selectable) |
| Resolution | Up to 13-bit (4 mg/LSB at ±2 g) |
| Current Consumption | ~40 µA (measurement), 0.1 µA (standby) |
What You Can Build With This
- Tilt‑based game controller using Arduino
- Pedometer or step‑counting wearable
- Vibration alarm for machine condition monitoring
- Orientation‑based screen rotation for portable displays
Compatibility
Works directly with any 3.3 V or 5 V microcontroller that supports I2C or SPI. Commonly paired with Arduino Uno, Nano, Mega, ESP32, ESP8266, and Raspberry Pi. The on‑board voltage regulator and level shifters allow safe connection to 5 V logic without extra components.
Wiring Notes
For I2C, connect VCC to 3.3 V/5 V, GND to GND, SDA to A4, and SCL to A5 (Uno). In SPI mode, use CS (pin 10), SDO (MISO), SDA (MOSI), and SCL (SCK). Keep wiring short and add 4.7 kΩ pull‑up resistors on SDA/SCL unless already present on the module.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, it works with 3.3 V and 5 V Arduino boards. Use the Adafruit ADXL345 or SparkFun library for quick I2C/SPI communication.
What is the default I2C address?
The default address is 0x53. To change it to 0x1D, connect the SDO/ALT pin to VCC.
Can it detect tap and double‑tap?
Absolutely. The ADXL345 has built‑in interrupt functions for single tap, double tap, free‑fall, and activity/inactivity detection.
