Replacement: SEN-10537. This board has been replaced by a newer version. The new version replaces the PIC with an ATMega and the MMA7260Q with the MMA7361. This page is for reference only.
Description: The SerAccel v5 is a 3 axis accelerometer up to +/-6g with a simple serial interface. The latest SerAccel development, version 5 has many new improvements including variable baud rate, a factory reset command, and a complete triple axis measurement system based on the newly released MMA7260Q sensor from Freescale. Power is gained from any RS232 port (including USB-to-RS232 converters) so no external power supply is needed. The onboard PIC (16LF88) runs at 10MHz and outputs three different types of outputs including calculated, binary, and raw outputs. The SerAccel v5 has software configurable settings to select between 4 sensing ranges (+/- 1.5, 2, 4, and 6g), as well as a software selectable measurement frequency (0-590Hz).
The SerAccel outputs real-time accelerations from 9600 to 57600bps using visible ASCII characters. The SerAccel is compatible with any RS232 Comm port in conjunction with any terminal program (Hyperterminal, VB Programs, or anything else that can read the comm port). Works with USB-RS232 converters.
Device comes fully assembled and tested.
