Sound Level Meter Data Logger with type 1 microphone

The NSRT_mk3_Dev is a sound level meter with a dust-protected type I digital MEMS microphone and USB connectivity. This instrument is similar to the NSRT_mk3 in form, function and performance but is aimed at developers and OEMs.

The Sound Level Meter Data Logger NSRT_mk3_Dev is similar to the NSRT_mk3 in form, function and performance, but has been redesigned with developers in mind. This instrument is designed to be used while connected to a host such as a Raspberry Pi. In such applications the NSRT_mk3_Dev is driven by a custom application. Such application can easily configure the instrument read its data in real-time, and perform other custom functions as intended by the developer. The NSRT_mk3_Dev cannot be used in standalone mode.

The main differences between the NSRT_mk3 and the NSRT_mk3_Dev are:

1. The NSRT_mk3_Dev does not have a battery. It is meant to be used while connected to a host and powered by the host’s USB port.
2. The NSRT_mk3 does not have any non-volatile memory. It is intended to be connected to a host and driven by a custom application. Such application will use the host’s non-volatile memory as the situation requires.
3. The NSRT_mk3_Dev offers a Virtual Com Port interface (through its USB connection) for communication with the host. The communication protocol is open and documented.
4. The NSRT_mk3_Dev has been tested on Windows and Linux. It will work on any platform that provides a generic USB CDC-class driver.
