Accelerometer Three-axis Sensor Module GY-61 ADXL335

Accelerometer Three-axis Sensor Module GY-61 ADXL335

The GY-61 ADXL335 is a compact, low-power 3-axis analog accelerometer module built around the Analog Devices ADXL335 sensor. Designed for measuring both static (e.g., gravity) and dynamic (e.g., motion, vibration) acceleration, it outputs analog voltages proportional to acceleration along the X, Y, and Z axes. The onboard 3.3V voltage regulator allows the module to be powered with either 3.3V or 5V, making it suitable for a wide range of microcontroller systems such as Arduino.

Package Includes:

  • 1 x GY-61 ADXL335 3-Axis Accelerometer Module
  •  Male Header Pins (for soldering)

Pinout:

GY-61 ADXL335 Pinout

Pin Name Description
1 VCC Power supply (3.3V to 6V)
2 GND Ground
3 XOUT Analog output for X-axis
4 YOUT Analog output for Y-axis
5 ZOUT Analog output for Z-axis

Wiring with Arduino:

GY-61 Pin Arduino Pin
VCC 3.3V
GND GND
XOUT A0
YOUT A3
ZOUT A4

Calibration Tips:

  • When flat: Z-axis ≈ 1g; X and Y ≈ 0g
  • Rotate the sensor to calibrate ±1g and 0g for each axis

Arduino Code Example:

const int xpin = A0;
const int ypin = A3;
const int zpin = A4;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int x = analogRead(xpin);
  int y = analogRead(ypin);
  int z = analogRead(zpin);

  Serial.print(((float)x - 331.5) / 65 * 9.8); // X-axis in m/s²
  Serial.print("\t");
  Serial.print(((float)y - 329.5) / 68.5 * 9.8); // Y-axis in m/s²
  Serial.print("\t");
  Serial.print(((float)z - 340) / 68 * 9.8); // Z-axis in m/s²
  Serial.println();

  delay(1000);
}

Applications:

  • Tilt and orientation sensing
  • Motion tracking
  • Vibration monitoring
  • Robotics and drones
  • DIY accelerometer-based control systems

 

 

Features

  • LoRa SX1276 Wireless Module: Built around the SX1276 chip, the module employs LoRa technology, allowing for long-range data transmission and excellent penetration capabilities.
  • Configurable Output Power: The module's output power can be adjusted from +13 to +20 dBm (up to 100 mW) through software settings, providing flexibility in balancing communication distance and power consumption.
  • Low Power Consumption: During transmission, power consumption ranges from 50mA (+13 dBm) to 150mA (+20dBm), while in listening mode, it requires approximately 30mA, making it energy-efficient for battery-operated applications.
  • AES-128 Encryption Support: The module offers AES-128 encryption, ensuring secure and private data transmission, making it suitable for applications that require data confidentiality.
  • Multipoint Network Capabilities: It supports multipoint networks, allowing the establishment of individual nodes within the network for seamless and efficient communication.
  • Wide Power Supply Range: The module can be powered with a voltage range from 3V to 5V, making it compatible with various power sources and microcontrollers.

NOTE: It is important to solder a 16cm length of cable to the antenna pin before using it since not connecting any antenna can damage it. Optionally, the board has pads to solder an SMA connector with antenna thread.
