Frank (forum user DD4WH) made a microSoundRecorder to log both audio and environmental data to an SD card.

The recorder uses a BME280 sensor to log temperature, air pressure and humidity, and a BH1750 sensor to log light intensity.  It also includes a digital microphone to capture audio.

The project made use of Walter’s (forum user WMXZ) environmental sound recorder library.  Additional information on how to connect the sensors to the Teensy can be found on this GitHub page.
