Wireless Sound Level Sensor

Data Harvest

Product Description


This sensor accurately measures sound pressure level in decibels (dB) or examining the frequency content of sound in waveform (mV). The A filter used in the dBA range measures mid-range frequencies to approximate the normal human ear in the range and intensity that it ‘hears’ sounds. The C filter (dBC range) suits low and high frequency sound levels.  


Bluetooth | USB | Huge Battery Life | Independent Logging




Here are just a few example practical ideas you can achieve by using the Wireless Sound Level Sensor.

  • Speed of sound
  • Sound insulation
  • Decay of sound with distance
  • Field Studies
  • Noise pollution indoors and outdoors
  • Effect of sampling rate on sound quality
  • Sound Waves: monitoring the effect of altering frequency and amplitude, waveforms of musical instruments, beat patterns, etc.
  • Voice recognition, the sound of a single letter.



Ranges Sound Level in 2 ranges: (1) 40 to 110 dBA and (2) 40 to 110 dBC, Sound Waveform in 2 ranges: (1) ±25 mV, (2) ±100 mV.
Connectivity USB & Bluetooth

Seriously Smart Wireless Bluetooth Sensors 

Designed with new and existing customers in mind!

A new Smart Wireless range of science sensors that also function as data loggers in their own right using Bluetooth or USB connectivity. The new Bluetooth wireless sensors include a huge battery life and can be mixed & matched with existing SmartQ Sensors & Data Loggers!

Works with SmartQ

Our wireless sensors can be used in combination with other Smart Wireless Sensors or data loggers in the EasySense range, even more amazingly is that with the addition of a V-Hub sensor link you can continue to enjoy using your existing SmartQ sensors at the same time!

The Power of Smart Wireless

Our Smart Wireless sensors build on the design of our legendary intelligent SmartQ Sensors but adds Bluetooth wireless connectivity allowing users to connect to tablets and mobile phones using the new EasySense2 Software. 

Digital Technology
Our digital sensor technology brings science to the classroom providing you with a robust, accurate and repeatable teaching experience from the start.


Auto Calibration
We have taken the hassle out of setting up your experiments with our pre-calibrated, auto identify sensor technology, every sensor is ready to use out of the box.


USB Charging
Our Smart Wireless sensors are powered by an internal battery and can be charged via a standard USB charger.


Designed for Mobile
With the included Bluetooth connectivity the new Smart Wireless Sensors can connect to Tablets, Mobile Phones, Laptops and Desktop Computers


Smart Connectivity

Not only do the Smart Wireless Sensors connect to multiple tablets and mobile devices via Bluetooth but they can also connect directly to a desktop computer and be used just like a traditional data logger whilst offering faster data transfer rates.
