Specification

Parameters:

function description

Working mode

1) Normal work mode The chipset goes into normal working mode when step motion is detected. The Step-out pin is in low level usually, it will output one high pulse with one step motion, and the high level of the pulse is around 50ms.


Sleep mode

If the module doesn’t automatically come to sleep status within 20 seconds, the G sensor doesn’t work. the entire pedometer chipset in low power consumption mode, then the current is less than 4uA!
