Overview
The Smart Wireless Sound level sensor is a two channel sensor that can be used to measure
accurately sound intensity level in decibels (dB) and examine the frequency content of the sound in
waveform (mV). Both channels can be recorded at the same time.
It has a sufficiently fast response to capture waveforms and allow for the measurement of speed of
sound using one Sound sensor.
The electret microphone used in this Sensor is equally responsive to all sound frequencies within the
20 Hz to 10 kHz range and can measure both transient and continuous noise.
The sensor is both USB and Bluetooth compatible. Using Bluetooth the sensor can wirelessly connect
to mobile devices such tablets and mobile phones as well as desktop or laptop computers giving
students the ability to run experiments independently without being tethered to a traditional data logger.
See the EasySense2 user manual system requirements for further details.
The sensor is supplied with a mini USB lead (1 m standard A to standard mini B).
