The wGT3X-BT is intended for use in applications where quantifiable measurement and storage ofphysical movement is desired.wGT3X-BT Technical DetailsActiGraph wGT3X-BT activity monitors contain a 3-axis MEMS accelerometer with a dynamic range of +/- 8 G.Acceleration data are sampled by a 12 bit analog to digital converter at user specified rates ranging from 30 Hz to100 Hz and stored in a raw, non-filtered/accumulated format in the units of gravity (G’s). Data are stored directlyinto a non-volatile flash memory.OverviewBluetooth® LEEnables wireless device features (heart rate monitoring, proximitydetection) and communication with ActiGraph mobile applications.Wear time sensorAutomatically detects if a wrist worn device has been removed forsimplified compliance monitoring and data cleaning.Ambient Light SensorProvides minute-by-minute light intensity values (in lux) alongsideactivity information, helpful for examining the relationship betweenenvironment and activity and sleep behaviors.DimensionsWeightSample rateBattery lifeData storage/MemorySpecifications3.3 x 4.6 x 1.5 cm19 grams30-100 Hertz25 days*240 days/4 GBDynamic rangeCommunicationWater resistanceWear locationWarranty+/- 8GUSB, Bluetooth® LE1 meter, 30 min.Wrist, waist, ankle, thigh1 year* Wireless disabled, 30 Hz sample rate
