3 Axis Acceleration Sensor Board are manufactured by Sure Electronics. Mainchip is MMA7260Q from Freescale. It is a first generation 3 axis acceleration sensor. User could get acceleration value of X, Y, and Z axis. And it is widely used in shock, slope, and moving detection. Output sensitivity could be select by simply set voltage level on few pins. The measure range is selectable in 1.5g, 3g, and 6g. It only cost 3uA in sleep mode, and the work current is as low as 500uA. Sure Electronics provide this board for those who want to use such sensors but can not solder them, with this small butterfly board, you could start your design quickly. It is easy to be integrated in 5V systems and 3.3V systems, and the cost is very low for batch use.
For more information of MMA7260Q from freescale, you could take reference from the documentation in the chip’s PDF file. It could be found in Freescale website and the accessory CD-ROM.
The output of MMA7260Q is analog mode, so you need a A/D converter to read the acceleration value. Simple sample codes are provided to help you to understand how to integrate it to your design.
We will release a tiny microcontroller demo board which could be connected to this acceleration board, through the 2 rows of bare connectors. Then this board could be convert into a digital interface one.
