This is a three axis accelerometer designed for E-Textiles. Based on the ADXL335 MEMS accelerometer from Analog Devices, this Accelerometer can detect joint movement as well as inclination and vibration.
The ADXL335 outputs a 0V to 3V analog signal on each of the X, Y, and Z axis. You will need to convert this analog voltage to a gravity amount and use trigonometry to calculate a true ‘angle’. If you are not looking for tilt, it is very easy to use this sensor for basic motion sensing.
They’re even washable! These PCBs are red in colour.
Jargon buster
Plain-language definitions for the technical terms used above.
- e-textiles
- Electronic textiles are fabrics or clothing that include electrical parts such as conductive thread, sensors, LEDs, or small controllers. This matters because parts for e-textiles need to survive bending, sewing, and sometimes washing.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- MEMS accelerometer
- A tiny motion sensor made using micro-electromechanical systems technology that measures acceleration and tilt. In a compass module, it helps correct the heading when the board is not perfectly flat.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
