Graphical Analysisā¢ GW is a tool for science students to collect, graph, and analyze data from Vernier Go WirelessĀ® sensors.
Sensor data-collection support:
ā¢ Vernier Go WirelessĀ® Temp and Go Wireless pH sensors
ā¢ Vernier Go Wireless Heart Rate and Go Wireless Exercise Heart Rate monitors
ā¢ Vernier LabQuestĀ® sensors used with Go Wireless Link or LabQuest Stream interfaces
Additional experiment options:
ā¢ Data Sharing via Wi-Fi connection to LabQuest 2 or Logger ProĀ® 3
ā¢ Built-in Sensors (accelerometers)
ā¢ Manual Entry
Note: Sensor data collection and Data Sharing require the purchase of hardware from Vernier Software & Technology. Built-in sensor and manual entry of data can be performed without a hardware purchase. For more information on Data Sharing, visit http://www.vernier.com/css
