[Tinyos-help] Conversion formula of Accelerometer value.

[André Miguel de Almeida Marrão Rodrigues]

Hi

Usually you should get a 12 bit value (ADC12). So the range should be between 0 and 4096.
If it's the case you should calculate: value read / 4096 * 3  -  1.5 (http://www.easysen.com/support/Datasheets/Accelerometer_MMA6260Q_Freescale.pdf)

Regards,

André
