Edu-Logger Sound Logger Sensor

The Edu-Logger Sound Logger Sensor can be used to determine the frequencies of tuning forks and wind-chimes and to calibrate simple electronic signal generators. 

The Edu-Logger Sound Logger Sensor can be operated with two sound sensors, the velocity of propagation of sound in various media can be determined by timing a pulse travelling between them.

The Edu-Logger Sound Logger Sensor has two modes of operation. In slow mode it can be used to measure sound-pressure level in decibels. In fast mode it can be used to compare different sources of sound, their waveforms can also be displayed.  The sound sensor is located in a plastic box accessible to the atmosphere via a hole in its side.

What makes the Edu-Logger Sound Logger Sensor different to other systems?

• Very simple operation 
• Unbeatable value for money 
• System allows wireless connection 
• Robust hardware and attractive design 
• Each sensor is in itself a full data acquisition system 
• No cable clutter and therefore a very simple construction of experiments 
• The modular plug and play system allows the connection of sensors in a chain, in any order

Features of the Edu-Logger Sound Logger Sensor

• Saves up to 5 experiments in its flash memory 
• Calibration is done by pressing a push-button
