HOBO UX90 Light On/Off Data Logger

Ideal for energy audits and light usage analysis in buildings, this data logger monitors indoor light changes using an internal sensor and records light on/off conditions. Auto-calibration of on/off thresholds ensures reliable readings, and user-adjustable sensitivity control accounts for low/high light level conditions. The 128 KB memory records up to 84,650 measurements. Requires either HOBOware (available as a free download), or HOBOware Pro software (sold separately).
