Adafruit Triple-Axis Accelerometer Breakout Boards
- Adafruit 2809, The Adafruit LIS3DH Triple-Axis Accelerometer is a neat 3-axis accelerometer with adjustable sensitivity & a choice of either I2C or SPI bus connectivity. Select from ±2, 4, 8 or 16g sensitivity; ±2g gives a higher resolution for slow movements while ±16g is best for high speed tracking. It can be configured to detect a single tap & free-fall, either of which can be configured to toggle an external interrupt pin to signal your microcontroller. As a bonus the board has 3 x analogue inputs with 10-bit resolution & you can read the values from the chip's on board registers. Supplied as a fully assembled & tested accelerometer board plus a strip of 0.1in. pitch header pins for you to solder on as required. Adafruit provide a free tutorial to help get you started.
