Wired sensors
Sensors that connect to data acquisition devices via cable.
Use the Microphone to display and study the waveforms of sounds from voices and musical instruments. It also works well for speed of sound experiments.
Specification
- Frequency Range: approximately 100 Hz to 15 kHz
Modes: digital status, movement, length of passing object, consecutive gates, pendulum from the center and "gates and object". Grip distance 75mm, Reaction time 5 ms.
Tripod mount included.
Works with LabQuest, LabQuest2, LabQuest3, LabQuestMini and LabQuest Stream data collectors. Does not work with GoLink data collector!
The Sound Level Sensor is a simple, easily-operated sensor to measure and investigate sound levels in classroom environments.
