activPAL™ micro, one of the PALfamily of products
The activPAL™ micro is available in two models:
- activPAL4 (released 2018)
- activPAL3 (released 2014) legacy support
Both models are the same size, 23.5mm wide, 43mm long and only 5mm thick. The activPAL micro weighs 9.5grams.
The main difference between the activPAL4 and the activPAL3 is that the activPAL4 stores the raw acceleration data as a high resolution number (10bits per sample with a range of +4 to -4g). It is however compatible with the activPAL3 which has a lower resolution and range (8bits per sample across a range of +2 to -2g). The activPAL4 is warranted for a minimum 14 day recording capacity, the activPAL3, only 7 days.
The activPAL3 is a legacy support version that is maintained to provide continuity for existing projects. We recommend the activPAL4 is chosen for new projects.
