ADXL335 Accelerometer Analog XYZ axis

ADXL335 3-Axis Analog Accelerometer Module
The ADXL335 measures the force of acceleration—whether that’s from being moved (dynamic) or from the pull of gravity (static). Because it can "feel" gravity, it is exceptionally good at detecting which way is "down," allowing you to use it as a highly accurate tilt sensor.

 
Why it’s a Maker Favorite:
• True Analog Simplicity: There are no registers to configure or baud rates to set. You simply connect the X, Y, and Z pins to your microcontroller's analog input pins and read the values.
• 3-Axis Sensing: It tracks movement in 3D space. Whether the device is tilted, shaken, or dropped, the ADXL335 captures the change across all three dimensions simultaneously.
• Low Power, High Sensitivity: Drawing only about 350–500 µA, it is ideal for wearable devices or battery-powered drones where every milliamp counts.
• Wide Voltage Range: While the sensor chip itself runs on 3V, the module usually includes an onboard regulator, allowing it to play nicely with both 3.3V and 5V systems.

 
Technical Capabilities:
• ±3g Measurement Range: This is the "Goldilocks" range for human-scale movement. It’s sensitive enough to detect subtle tilts but robust enough to handle the vibrations of a motor or a small impact.
• Built-in Filtering: The module includes capacitors that act as low-pass filters. This helps "smooth out" the data, reducing the electrical noise that can often make motion data look "jittery."
• Real-Time Response: Because there is no digital communication overhead, the response is near-instantaneous, which is critical for drone stabilization or fast-paced gaming interfaces.

 
Best For:
The ADXL335 is the go-to for robotics motion control, impact detection, tilt sensing, and gesture-based interfaces. If you need to know if a robot has tipped over or how fast a handheld device is moving, this sensor is the simplest way to get that data.
