Our environmental sensor monitors ambient light, temperature, relative humidity, and pressure to incorporate with your PiezoSleep sleep, wake, and activity data.

–  Light level (lux)

– Temperature (degrees Fahrenheit)

–  Relative Humidity (percent)

– Pressure (inches of Mercury)

The environmental sensor connects to the computer used for PiezoSleep recordings via a USB port. Position the sensor near the cages being recorded. At the start of a recording, a prompt in PiezoSleep will ask if you are recording with an Environmental Sensor.  When “yes” is selected, the sensor collects environmental data in two-second intervals.

A file is generated over the recorded period with the extension “.Env” which imports into SleepStats analysis software along with the files generated from piezoelectric data. The lux data can be used to adjust light and dark onset times in SleepStats.  Users can overlay light, temperature, relative humidity, or pressure data in the single-channel sleep/wake Decision Statistics graph view. Environmental data can be exported in user-selected intervals for analysis with other exported data such as sleep, wake, or activity.

See the environmental sensor data in action in our SleepStats video at minute 9:30.
