Thank you for purchasing the Smart Wireless Sound Level Sensor. We pride ourselves on producing high quality products that meets with the demands of the busy classroom environment. If you have any problems using this sensor, please read this documentation in full before contacting the Data Harvest support team. 


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).
