General Description
The SPT0004 is an low-power accelerometer module specially designed for pedometer application. This solution can be easily integrated into systems by a digital interface. The SPT0004 consists of a single axis acceleration sensor with integrated driver to provide pulse output for step detection and a digital output for different tilt angle. All step calculation and noise filtering are done by the ASIC.
