Hi,
I am using ANT+ sensors linked with Unity3D for a rehabilitation project and have tried several commercially available sensors who all seem to share the same fundamental problem (in the context of the project) i.e. that anything below 25 rpm will not activate the sensor. Between 25rpm and 50rpm there is significant data loss, which is evident from the frequent null-readings even though connection is established. I have tried both cadence and speed sensors: Wahoo Speed, Wahoo Cadence, Coospo cadence/speed.
Most producers have indicated an upper measurement extremum (about 300rpm and 120km/h), but not really a lower cutoff.
Does anyone know if this is hardware standards, or are aware of some sensors with high sensitivity to slower changes in velocity or revolutions? users will frequently have empaired motor skills, so detecting small changes is paramount
any help will be greatly appreciated!
