Why does my sensor have no data after I wore it?
It can be frustrating when you go to transfer throwing data from your sensor but there is no data to transfer. Luckily, it usually isn't a problem with the sensor. Here are a few tips to make sure your sensor is ready to track all of your throws.
The most likely reason a sensor will have little or no data to transfer after wearing it during a throwing session is that the sensor's battery was dead. Your sensor does not have an on/off button and is always on the lookout for a throw to occur. For that reason, we recommend leaving your sensor on the charger until you are ready to put it in the sleeve and begin throwing. See What is the battery life of the motus sensor? for more tips on extending the battery life of your sensor.
Another common factor for coaches with a large team is that the player didn't actually wear the sleeve or didn't have the sensor in the sleeve during their throwing session. It can be challenging to ensure compliance when you are unable to be hands on with each player each day. Effectively communicating the need to wear the sensor during all throwing sessions is the best way to ensure the sensor is used to track your athletes' throws. Showing the players the wealth of information the sensor can deliver in the app and DASH is a great way to explain the importance of workload monitoring. You can also give the player greater access to their data so that they can also track their workload. When adding new athletes to your roster, you provided an email and password for each athlete. The athlete can use these credentials to log in to the motusQB app to view their data and even transfer the data themselves for you to review later.
Improper sensor placement can also affect the quality and quantity of data recorded on the sensor. See Wearing Your motusQB Sleeve or Wristband to ensure the sensor is oriented correctly in the sensor. Finally, the sensor is designed to pick up real effort overhand throwing motions. It may not register throws that are performed using your non-dominant throwing arm, shovel passes or underhand throws, short flicks of the wrist with no follow-through, or throws performed by young children (younger than about 8) without full control of their throwing motion.
Regardless of the underlying cause, you should still account for the missed workload by adding simulated throws to your account.
