| # Temi VOC/Smell Datasets (2025) |
|
|
| This dataset includes processed smell collection metrics recorded by 2 versions of the SmartNanotubes [Smell Inspector](https://cdn.prod.website-files.com/67a0b744e71371ac7cb22fda/6810bcae6ccbea1631617e8b_SNT_Manual_Smell%20Inspector_V2.1.0.pdf). The sensor was attached to the tray of a [Temi robot](https://www.robotemi.com/product/temi/), which roamed our office on a set path for around 5 months. The robot patrolled every hour and recorded a few hundred smell data points on each run. At each smell data point (in the `processed/new-sensor.csv` file), the robot also took a picture using its front top camera of the area that it was in. |
| Old Sensor: Firmware version 3.0.1 |
| New Sensor: Firmware version 2.1.1 (we replaced the old sensor with the new sensor due to faults in the old sensor, even though it was a downgrade in firmware version) |
| Raw and processed CSV data and code for cleaning can be found on [github](https://github.com/Kentucky-Open-Science/Temi-VOC-Datasets). |
