Hi,
I was searching for an accelerometer based on following parameters:
1. Digital
2. High g (>16g)
3. Cheap (<5 USD)
4. Commercially available
5. Commonly used (arduino support)
Can anyone suggest it?
Thanks.

 

The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2 C digital interface.

I have used them on PIC & Arduino.
