The sensor data were collected by four different instruments. The reaction probe measured UV A and UV B wavelengths, stir rate, temperature, and pressure. The system extracted the average RGB components of the images captured by the submersed camera. The environmental sensor measured light, humidity, temperature, and pressure. The Vernier thermometer provided a more accurate measure of temperature than the reaction probe (±1 °C versus ±3 °C). This temperature data was therefore used in preference to the temperature data from the probe.
