Keyestudio MMA8452Q Module Triaxial Digital Acceleration Tilt Sensor for Arduino

The Keyestudio MMA8452Q Module is a smart, low-power three-axis capacitive acceleration sensor designed for precise motion and tilt detection in your microcontroller projects. Offering 12-bit resolution and flexible programmable options, it is an excellent choice for South African students, makers, and hobbyists building smart devices or wearable technology.

Smart power-saving interrupts

The module features two programmable interrupt pins linked to six interrupt sources, including an inertial wake-up signal. This allows your main processor to remain in a low-power sleep state instead of constantly polling for data, saving overall system energy.

Adjustable dynamic range

Tailor the sensor to your project's specific needs with user-selectable full-scale ranges of ±2g, ±4g, or ±8g. It supports both 12-bit and 8-bit digital outputs, delivering either high-pass filtered or raw data in real time.

Embedded motion detection channels

With dedicated hardware channels for free fall, pulse, and shake detection, this sensor simplifies complex motion profiling. It also features transverse and longitudinal direction detection with built-in lag compensation.

Flexible power and communication

Operating on a supply voltage of 1.95 V to 3.6 V with an I2C interface running up to 2.25 MHz, this board integrates seamlessly into low-voltage setups. Power consumption ranges from a tiny 6 µA up to 165 µA depending on your output data rate.
